Spatial Stress-Deformation Analysis for Installation of a Diaphragm Wall

Abstract

There is an escalating need for acceptable techniques to estimate building settlements associated with the trenching process of diaphragm walls. Prediction of the deformation patterns resulting from in-situ wall installation can be achieved through monitoring more case histories and upgrading the available analysis techniques by rigorous evaluation of the measured data. The objective of the present research is to present a three-dimensional back analysis of measured building settlements compiled during the installation of a diaphragm wall in Greater Cairo. The numerical analysis showed that building settlements in the vicinity of the diaphragm wall trench depend predominantly, among other factors, on the foundation type of the proximity buildings and the paneled construction of the wall.
