SECTION-B
2) What are the advantages and disadvantages of plate load test?
3) A rectangular foundation 2m ? 3m transmits a pressure of 360 kN/m

to the underlying
soil. Determine the vertical stress at a point 1 meter vertically below a point lying outside
the loaded area, 1 meter away from a short edge and 0.5 meter away from a long edge.
4) List the assumptions made in Terzaghis bearing capacity theory.
5) Give the structure and characteristics of montmorilonite clay minerals.
6) For flow perpendicular to stratification in soils how is equivalent permeability calculated.
Derive the relevant expressions.

SECTION-C
7) Write short notes on the following :
a) Zero air void line and its significance.
b) Logarithmic time fitting method.
8) List and briefly explain the different types of machine foundations .Illustrate with neat
diagrams.
9) A 60 m high tower rests on 3 legs which form an equilateral triangle of sides 8m each.
The load coming on each leg may be considered as equivalent to a 300kN point. Using
boussinesq's theory compute the vertical stress increase at a point 2m deep vertically
below one of the legs.
