A long retaining wall is braced by wood shores set at ang angle of 30° and supported by concrete thrust blocks as shown. The shores are evenly spaced, 3m apart. For analysis purposes, the wall and shores are idealized on the second image. Note that the base of the wall and both ends of the shores are assumed to be pinned. The pressure of the soil against the wall I assumed to be triangularly distributed, and the resultant force acting on a 3-meter length of the wall is F= 190KN.
