4TH YEAR – SEM 1- QUESTION BANK – MID 1
Unit - 1
1. a) Describe with the help of a neat sketch the wash boring method of subsoil exploration. In what type of soils this method is recommended? What are the limitations of this method?
b) Explain how the standard penetration test is conducted?
2. a) Describe open excavation methods of exploration. What are their advantages and
Disadvantages?
b) Explain and discuss the various factors that help to decide the number and depth of bore holes required for subsoil exploration.
3 a) What is the object of Exploration Program and list out the phases of the
Exploration program and explain in brief?
b) Write short note on depth of Exploration and how can you fix the depth of boring in different case of Foundations? i.e Shallow and Deep Foundations.
Unit-2
4. a) Describe briefly about the “Plate Load Test”?
b) Describe briefly about the “Pressure meter Test”?
5 a) Compute the factor of safety of an infinite slope in steady seepage condition.
Take unit weight of the saturated soil as s and submerged unit weight as b.
b) How is the slope analyzed using Swedish circle method? Derive an expression for the factor of safety.
6 a) Computer the factor of safety of an infinite slope in cohesionless soil?
b)Describe about the different types of slope failures ?
Unit-3
7 a) Derive the equation for maximum passive earth pressure using the Mohr envelope. b) Calculate the total active earth pressure on a retaining wall of 9m height. The retaining soil has a 120 surcharge angle, a unit weight of 19 kN/m3, an angle of internal friction of 240, and a cohesion of 10 kN/m2. Also calculate the height of the line of action of the total pressure from the bottom of the wall. Neglect negative pressure when calculating the total pressure.
8 a) Write brief critical notes on “Taylor’s Stability Number”?
b)Write brief
