Ground vibration due to pile driving is a long-lasting concern associated with the foundation construction industry. It is of great importance to estimate the level of vibration prior to the beginning of pile driving, to avoid structural damage, or disturbance of building occupants. In this study, an axisymmetric finite-element model that utilises an adaptive meshing algorithm has been introduced, using the commercial code Abaqus, to simulate full penetration of the pile from the ground surface to the desired depth by applying successive hammer impacts. The model has been verified by comparing the computed particle velocities with those measured in the field. The results indicate that the peak particle velocity at the ground surface does not occur when the pile toe is on the ground surface; as the pile penetrates into the ground, the particle velocity reaches a maximum value at a critical depth of penetration. Some sensitivity analyses have been performed to evaluate the effect of soil, pile and hammer properties on the level of vibrations. The results show that increase in pile diameter, hammer impact force, soil–pile friction and reduction in soil elastic modulus can increase the peak particle velocity.

    Soil is a non-homogenous blend of many materials. There are many factors that need to be considered when digging trenches in soil. To analyze the stability of unsupported trenches, the method selected will depend on the critical nature of the project, economics, and the amount of time available for design. For shallow utility line excavations, where time and economics are at a premium, a rapid technique for evaluating the critical depth and the maximum safe slope is required. The maximum safe slope is identified as the "angle of repose." The use of stability charts or tables coupled with a few simple equations is the most efficient approach.…

    The Direct Shear Test is an investigation used by geotechnical engineers used to measure the shear strength properties of a soil. It is noted that the shear strength of a material is a term used to describe a materials ability to resist failing in the direction parallel to the applied force, and therefore an important soil property to be noted by engineers. In this lab test ‘Sydney Sand’ is used to determine the relationship between a given load and a change in cross-sectional area and also show the friction angle of the soil specimen, by testing the sample using what is commonly known as a shear box.…

    Mass movement is defined as the movement of surface material from a vulnerable slope, under the force of gravity. The ultimate cause of these events is slope failure, which is initiated primarily by the topography of the land. Where a slope is present, it is possible for mass movements to occur. However, many factors combine in order to trigger such an occurrence or worsen the landslide or mudslide, by either reducing the shear strength of the slope, or increasing the shear stress. Ultimately, the main problem occurs when mass movement presents a hazard to the livelihoods of people. This issue arises because humans develop the area around slopes. It is therefore necessary to consider both the human and physical factors which contribute to impacts from mass movements.…

    The objective of this brief guide is to inform promoters of civil engineering and building projects of the importance of adequate site investigation for the successful completion of their project. It indicates what a site investigation is likely to comprise, the important role of the promoter, and the risk to the project of undertaking an inappropriate or inadequate site investigation. The design of a structure which is economical and safe to construct, is durable and has low maintenance costs, depends upon an adequate understanding of the nature of the ground. This understanding comes from an appreciation of the distribution of the materials in the ground, and their properties and behaviour under various influences and constraints during the construction and lifetime of the structure. An adequate and properly structured site investigation is therefore an essential part of any civil engineering or building project. The Institution of Civil Engineers has published a guide Without Site Investigation Ground is a Hazard (Ref 1, Vol 1) which is primarily for clients and their non-geotechnical advisors. The guide’s purpose is to raise awareness of ground problems and highlight the consequences of inadequate site investigation. The executive summary states: Inadequate site investigation arises from the lack of awareness of the hazards associated with the ground, inadequate focus of finance, insufficient time and a lack of geotechnical (or geoenvironmental) expertise. It is concluded that a site investigation should be undertaken for every site, since without a properly procured, supervised and interpreted site investigation, hazards which lie in the ground beneath the site cannot be known. It should be noted that the terms site investigation and ground investigation have frequently been misused. A site investigation is the overall process of discovery of information, appraisal of…

    Ground Improvement Technique

    ABSTRACT The objective of this thesis was to gain a better understanding of the physical process of ground improvement by vibro-replacement and of how the induced changes in ground conditions affect the interpretation of seismic cone penetration testing used to assess its effectiveness. This was achieved by a combination of field testing and monitoring supported by numerical modelling of both the vibro-replacement process and of in situ testing. Field measurements were made of the input motions created by the vibrator and the induced response of the ground. The measured vibrator motions were input to a numerical model of the soil mass and the results of the analysis were compared to the measured data. The results of seismic cone testing before and after treatment at 15 sites and existing chamber test data were analyzed and additional numerical modelling of seismic cone testing in the post-treatment ground conditions was carried out. The study showed that the ground response to the vibrator attenuated with distance due to geometrical spreading and material damping. The direction of the principal horizontal acceleration changed with distance from the vibrator. It was shown that vibro-replacement creates a young, heterogeneous deposit comprising the native soil with increases in density and horizontal stress varying with distance from stiffer stone columns. If the induced heterogeneity is neglected when interpreting in situ test results, there will be some over-estimation of the soil properties close to the…

    Typically concrete shafts at construction sites which need pile integrity assessment have steel bar reinforcements in them and these reinforcements stick out 1.5 to 3 m10 ft above the pile top. depending upon other factors. In general PIT records obtained on piles without reinforcements exhibit a smooth record where the velocity has an initial impact pulse. Beyond this the curve tends to shift downward due to soil resistance before it reaches the toe showing a rise in the curve again. The above described is an ideal record rarely realized under field conditions. Small variations in the pile cross sections, bulges and defects tend to change the shape of the output record. While these can be analyzed and conclusions regarding the location of the defect or bulge or excessive soil resistance or lack of soil resistance can be arrived at, distortions caused in the record due to wave traveling through the reinforcement at a different frequency and the lateral vibration caused in the steel make it difficult to analyze records and arrive at conclusions.…

    The belief that an education is most valuable when it is used to serve one’s community has been instilled in me. This conviction and a natural aptitude for science and mathematics convinced me civil engineering was the most fitting career for me. In fact, they continue to be the driving forces in my pursuit of academic excellence as a senior at the University of Missouri (MU). I desire a degree in civil engineering not only because it is the most fulfilling way I can exercise my natural talents as a scholar, but because it also gives me the opportunity to solve challenges directly impacting my community. Upon receiving my Bachelor of Science in Civil Engineering, I plan to continue my education by pursuing a Master’s degree in Civil Engineering in the Geotechnical specialty. My interest in geotechnical engineering was sparked by topics such as the theory of consolidation, shear strength, and ground improvement methods introduced to me in my fundamentals of soil mechanics course. It was further cultivated when I began attending seminars presented by the geotechnical engineering program and participating in undergraduate research. I am interested in a broad range of topics including ground improvement methods, earthworks, and seismic response and would like to further my knowledge of concepts similar to these through my graduate program of study. During my four years at the University of Missouri, I have gained the qualifications and work ethic necessary to be a successful graduate student. These characteristics are exemplified by my contributions as an undergraduate research assistant in the geotechnical engineering program at MU. I began conducting research during the summer of 2008 with Dr. Greg Greene and have worked on projects focusing on driven pile foundations and slope stability. Currently I am…
