Geotechnical Engineering Fundamentals
Problem: Determine the dimensions (x4, x1 to x3 are fixed due to construction requirements) of the cantilever retaining wall that satisfy the required factors of safety against overturning, direct sliding and bearing capacity. The parameters are summarized in Table 1.
