Performance of a propped diaphragm wall in stiff residual soils

摘要

This paper presents performance of a propped diaphragm wall in stiff residual soils and weathered rocks of Singapore. Back-analysis using the finite element method has been carried out to study the effects of concrete cracking on the performance of the propped diaphrgam wall. The results of the finite element analysis suggest that after cracking is initiated, the use of linear elastic wall properties would lead to smaller lateral wall movement predictions, compared to an analysis that incorporated the effects of concrete cracking.
