Questions & Step-by-Step Solutions

What is the ultimate bearing capacity of a shallow foundation on saturated clay with a cohesion of 50 kPa and a depth of 1.5 m?
  • Step 1: Identify the given values. We have the cohesion (c) of the clay, which is 50 kPa, and we need to find the ultimate bearing capacity (q_u).
  • Step 2: Understand the formula for calculating the ultimate bearing capacity of a shallow foundation. The formula is q_u = c * N_c.
  • Step 3: Determine the bearing capacity factor (N_c) for saturated clay. For saturated clay, N_c is typically around 5.
  • Step 4: Substitute the values into the formula. We have c = 50 kPa and N_c = 5.
  • Step 5: Calculate the ultimate bearing capacity. Multiply 50 kPa by 5 to get q_u = 250 kPa.
