复合基桩桩顶荷载效应分析

Analysis of load-reaction for the top of complicated piles

分析了复合基桩中每根桩桩顶的受力分配状况,考虑到承台周边土的侧向釉竖向变形而引起的影响,并将其与不考虑土的侧向和竖向变形情况进行对比,从理论上定量解释了桩基规范 JGJ94-94中的有关规定,为筏板桩基础的计算打下了基础。

The load distribution of a top of complicated piles at strength situation is analyzed;it considers the lateral and vertical deformations' influences caused by soil around the platform;and compares its situation with that out of soil influence.This paper can play certain reference function for theoretically quantitative compares explanation for standard JGJ 94-94,and has laid a certain foundation for the calculation of piled raft foundations.
