ABSTRACT: Ground improvement techniques utilising Vibro methods, Deep Soil Mixing and Grouting technologies are finding increasing application in Malaysia to solve a broad spectrum of geotechnical problems.
This paper will describe recent applications in Malaysia for four separate projects – Jet Grouting to form stable cutter-head interventions for a tunnel project; Deep Soil Mixing to support deep vertical basement excavation with limestone interface for a commercial complex; Vibro Concrete Columns to found reinforced concrete tanks in former domestic landfill for a sewage treatment plant; Vibro Stone Columns to support high reinforced soil walls for a highway project. The importance of quality control measures are emphasized and available proving methods are also discussed. The case histories presented demonstrate that the techniques can provide effective solutions to challenging engineering problems.
1 Introduction
Malaysia has seen extensive growth for the past one decade with many infrastructure projects in the construction industry. Current technology affords many ground improvement techniques to suit a variety of soil conditions, structure types and performance criteria. These ground improvement techniques can offer alternative foundation systems to the conventional pile foundation systems. For more details on various available ground improvement nd techniques, the reader is referred to “Ground Improvement 2 Edition” book edited by Moseley & Kirsch (2004).
This paper illustrates four recent case histories
