Solution:
What is the seating drive in the Standard Penetration test on soil?
Solution:
A precast concrete pile has a size of 40cm x 40cm, and an ultimate load carrying capacity of 1200kN. The values of c' and α are 50kN/m2 and 0.6 respectively. What is the length of the pile?
Solution:
The percent reduction in the bearing capacity of a strip footing resting on sand under flooding condition (water level at the base of the footing) when compared to the situation where the water level is at a depth much greater than the width of footing, is approximately.
Solution:
During the subsurface investigations for design of foundations, a standard penetration test was conducted at 4.5 m below the ground surface. The record of number of blows is given below.
Assuming the water table at the ground level, soil as fine sand and correction for overburden as 1.0, the corrected ‘N’ value for the soil would be
