Optimum Design of CFG Pile Compound Foundation Based on Numerical Simulation Method

Abstract:

Aiming at the phenomenon of empirical selection in CFG pile compound foundation's design parameters, the computational models considering different pile length were built by numerical simulation software PLAXIS, whose background came from an actual highway engineering. The relation curves were plotted and analyzed concerning pile length with subgrade horizontal deformation, subgrade settlement, integral stability of embankment and end bearing force of pile, in the light of deformation and stress cloud graphs from post-processing results. The feasibility of pile length optimization in conventional design was judged synthetically according to above mentioned curves, and the optimized pile length was 2m shorter than the one of conventional design, which cut down construction cost. The construction practice indicates that there are not abnormal occurrence in subgrade treatment section during period of traffic operation.
