支盘桩受力机理及优化设计

Study on the mechanism and optimization design of branch piles

通过对工程支盘桩设计进行的FLAC3D数值模拟优化,分析出某工程的支盘桩设计还可进一步提高承载力、且在达到设计承载力要求的情况下减少支盘的可能性,优化方案在经济上和桩受力方面较原方案具有优越性,为今后支盘桩的设计提供了一种可行方法.

Through optimally designing branch piles by FLAC3D numerical simulation,the design of branch pile for a project can further improve its bearing capacity;and maybe it can reduce branches when reaching the designed bearing capability.The optimization is superior in economy and bearing capacity so as to provide a feasible method for designing branch piles.
