Question

Figure 1 shows a cross-section through an excavation in a deep sand deposit. The site engineer determined that the exaction is too deep for a cantilever sheet pile to perform as an economical option and recommended to prop a smaller thickness sheet pile wall by using wooden struts that are spaced 3 m along the length of the wall. You are the office design engineer and are given the sketch below and asked to determine the following:

  1. The distribution of the lateral pressure over the wall height.
  2. The total force that the retaining wall must resist.
  3. The loads (in kN) carried by the individual upper and lower props.
