Ques 18 Civil

A flownet below a dam consists of 24 equipotential drops and 7 flow channels. The difference between the upstream and downstream water levels is 6 m. The length of the flow line adjacent to the toe of the dam at exit is 1 m. The specific gravity and void ratio of the soil below the dam are 2.70 and 0.70, respectively. The factor of safety against piping is

1.67

2.5

3.4

Ques 19 Civil

The contact pressure and settlement distribution for a footing are shown in the figure.

The figure corresponds to a

rigid footing on granular soil

flexible footing on granular soil

flexible footing on saturated clay

rigid footing on cohesive soil

Ques 20 Civil

Which one of the following statements is NOT correct?

When the water content of soil lies between its liquid limit and plastic limit, the soil is said to be in plastic state.

Boussinesq's theory is used for the analysis of stratified soil.

The inclination of stable slope in cohesive soil can be greater than its angle of internal friction.

For saturated dense fine sand, after applying overburden correction, if the Standard Penetration Test value exceeds 15, dilatancy correction is to be applied.
