| 摘 要： | 引进圆孔扩张理论,模拟桩土相互作用,分析了散体材料桩复合地基的应力分布特征,并导出了桩体与土体承载过程中的应力应变计算公式,在此基础上,充分考虑了布桩方式对承载力的影响,根据两种典型的布桩方式,分别提出了一套散体材料桩复合地基面积比承载力计算方法,弥补了常规计算方法的不足.最后,给出工程算例,验证了计算方法的实用性.

| Abstract: | The theory of round-hole expansion was used to simulate the mutual actions between pile and soil.The stress distribution of discrete material pile foundation was studied,and a formula to calculate the stress-strain of pile and soil in loading process was deduced.On the basis of the above analysis,the effect of pile arrangement on the bearing was taken into consideration.According to two typical pile arrangements,a new area-rate calculation for bearing capacity of composite foundation on discrete material pile was put forward.The shortcomings of the traditional method have been overcome.The engineering examples were given and the use of the method was verified. |
