Heavy tamping

Solution:

The maximum unit pressure that a soil can withstand without rupture in shear or with excessive settlement of a structure is called

ultimate bearing capacity

safe bearing capacity

allowable bearing pressure

none of the above

Solution:

A plate load test is conducted on a sand using a 200 mm diameter plate. If the plate settlement was 10 mm at a pressure of 200 kPa, the settlement of a 4 m x 6 m rectangular footing at the same pressure will be:

50 mm

54 mm

58 mm

62 mm

Solution:

In foundation engineering, two footings are constructed on the surface of purely cohesionless soil. One is circular and the other is square. The diameter and side length of both are the same. What is the ratio of the ultimate bearing capacity of the circular footing to the square footing?

0.75

1.34

1.3

Solution:

Choose the correct option from the following, in the load settlement curve the safe load is taken as the least of the following:

Half of the load at which total settlement is equal to 10% of pile diameter

2/3 of the final load at which total settlement is 12 mm

2/3 of the load which causes a net settlement of 6 mm

1/3 of the final load at which total settlement is 12 mm

Solution:

A square footing of 2 m sides rests on the surface of a homogenous soil bed having the properties cohesion C = 24 kPa, angle of internal friction Φ = 25^o and unit weight γ = 18 kN/m³. Terzaghi’s bearing capacity factors for Φ = 25^oare N_c = 25.1, N_q = 12.7, N’_c = 14.8 N’q = 5.6 and N’_γ = 3.2. The ultimate bearing capacity of the foundation (in kPa, round off to 2 decimal places) is_____.
