The Finite Element Analysis of Pile-Raft Foundation after Optimization of the Raft Thickness

Article Preview

Abstract:

The numerical analysis model about pile-raft foundation was bulited by using finite element analysis software.The raft settlement, pile-top counterforce and soil counter force were analyzed by changing the thickness of raft .The thickness were 0.15m,0.20m,0.25m and 0.30m. It was said that it could effectively reduce the raft uneven settlement and realize the redistribution of the pile and soil counterforce by increasing raft thickness.After changing the pile length and the raft thickness The rule of raft settlement were analyzed. After the pile length and thickness of optimization,it was good to control settlement of the pile raft foundation.
