Embedment depths and sectional forces for propped walls with different foot supports.

In the following contribution the calculation of the embedment depth and the sectional forces is treated for the case of propped walls. A model for the earth support at the foot of the wall is presented including a free, a partly fixed and a fixed earth support. The determination of the embedment depth at the system with design loads is essentially easier compared to a calculation with characteristic quantities. Assuming a value for the rotation angle at the theoretical foot point of the wall permits to calculate the magnitude of the characteristic soil reactions. In the case that only permanent actions react on the wall, characteristic and design quantities are related by a simple factor. According to the recommendations of excavations a further simplification is possible, if the transient actions are increased by a factor and are treated as in the case of permanent situations.
