Stability of Supported Excavation
The effects were investigated of rigid lateral support and slurry support on the stability (mode of failure) and the size of the settlement zone for plane strain and axisymmetric excavations. From the results, the authors show that when immediate failure in saturated clays is of interest, changes in water content can be neglected. In the analyses presented here the lateral supports are assumed to be rigid and the soil is treated as a purely cohesive material. The results from upper bound calculations, finite element collapse analyses and centrifuge tests are presented and the solutions for the footing problem are interpreted for trench excavations. It was found that slurry support was more effective than rigid lateral support for axisymmetric excavations. The slurry support reduced the amount of surface settlement and also stabilised the trench against base failure. The results are presented in the form of stability charts.
