| 摘 要： | 为研究工程桩端扩张压力,对现有计算方法进行了改进。文章根据静压桩贯入机理,分析了静压桩的贯桩过程;并在模拟桩体贯入过程的基础上,建立了基于半无限圆孔扩张的压桩静力平衡方程,求得了弹性条件下桩端扩张压力的理论解答,同时进一步分析了桩端扩张压力与压入深度的关系。

| Abstract: | Based on the current research on pile jacking,the calculation method currently used for analysis of the expansion pressure at the tip of piles is improved,and the process of pile jacking is simulated and analyzed.A static mechanical equilibrium equation for pile jacking in semi-infinite space is established,and the solution to expansion pressure at the tip of piles is obtained under elastic condition.Moreover,the relationship between the expansion pressure and the depth of pile packing is discussed. |
