In this paper, based on the case of a soft soil excavations project in Zhongshan and the field measured data, the ABAQUS, a finite element software for engineering simulation, analyses the system which combines steel cement-soil pile and basement plate. Moreover it can simulate the deformation results and get the supporting stress model. The results show that the supporting effect of this system is remarkable. This simplified model calculation results are conservative. But there exists the problem of varying depth of excavations. As a result, the stress characteristics and design methods of th...
