What is the ultimate bearing capacity of a shallow foundation on a cohesive soil with a cohesion of 50 kPa and a depth of 1.5 m?
100 kPa
150 kPa
200 kPa
250 kPa
The ultimate bearing capacity (q_u) can be calculated using the formula q_u = c*N_c, where c is the cohesion and N_c is the bearing capacity factor. For a depth of 1.5 m, N_c is approximately 5.0. Thus, q_u = 50 kPa * 5 = 250 kPa.

Q
Q: What is the ultimate bearing capacity of a shallow foundation on a cohesive soil with a cohesion of 50 kPa and a depth of 1.5 m?
Solution: The ultimate bearing capacity (q_u) can be calculated using the formula q_u = c*N_c, where c is the cohesion and N_c is the bearing capacity factor. For a depth of 1.5 m, N_c is approximately 5.0. Thus, q_u = 50 kPa * 5 = 250 kPa.
Steps: 5
Step 1: Identify the given values. We have a cohesion (c) of 50 kPa and a depth of 1.5 m.
Step 2: Understand the formula for ultimate bearing capacity, which is q_u = c * N_c.
Step 3: Determine the bearing capacity factor (N_c) for a depth of 1.5 m. For this depth, N_c is approximately 5.0.
Step 4: Substitute the values into the formula: q_u = 50 kPa * 5.0.
