Excavations with Special Ground Plans
This chapter discusses excavations for circular, oval and rectangular ground plans. If the depth of a circular excavation is not greater than half of the diameter, the three‐dimensional earth pressure distribution from soil self‐weight and unbounded distributed loads is only insignificantly different to the earth pressure on an infinitely long retaining wall. The chapter presents approaches that apply to elliptically curved plans, if no more precise investigations are performed, for example with the aid of finite element methods (FEM). In principle, the retaining walls and the bracing or anchors of excavations with square or rectangular plans can be designed and constructed similar to those for elongated excavations. However, in the interests of economical design of structural members and a realistic deformation forecast, it is also permissible to take the earth pressure reduction caused by the three‐dimensional effect into consideration for cohesion‐less or at least stiff, cohesive soil.
