A cantilever sheet pile wall is driven into undrained clay and then back-
filled with granular soil. The groundwater table is at the dredge line.
The sheet pile and the soil characteristics are shown in Figure 7.57.
Determine:
(1) The depth of the embedment, D, using a factor of safety of 1.5 for
strength reduction.
(2) The maximum moment on the sheet pile.
(3) Given the allowable flexural stress of the sheet pile, all =
150 MN∕m², determine the section modulus of the sheet pile per
unit length.
