Q1. A uniformly distributed line load of 500 kN/m is acting on the ground surface. Based on Boussinesq’s theory, the ratio of vertical stress at a depth 2 m to that at 4 m, right below the line of loading, is
Explaination / Solution:

Due to UDL

Q2. Group I lists the type of gain or loss of strength in soils. Group II lists the property or process responsible for the loss or gain of strength in soils.
Group I                                                                        Group II
P. Regain of strength with time                                   1. Boiling
R. Loss of strength due to upward seepage               3. Thixotropy
S. Loss of strength due to remolding                          4. Sensitivity
The correct match between Group I and Group II is

Explaination / Solution:
No Explaination.

Q3. A runway is being constructed in a new airport as per the International Civil Aviation Organization (ICAO) recommendations. The elevation and the airport reference temperature of this airport are 535 m above the mean sea level and 22.65°C, respectively. Consider the effective gradient of runway as 1%. The length of runway required for a design-aircraft under the standard conditions is 2000 m. Within the framework of applying sequential corrections as per the ICAO recommendations, the length of runway corrected for the temperature is
