摘要
在桩基础中,当群桩受水平力作用时,如果群桩间距小于8倍桩径,则群桩水平力不等于各单桩水平力之和,在以往的研究中通常都是用实验来得到各桩水平力的较小值,P因子则是反映群桩承载力的典型方法,但是在这方面理论研究比较小,通过总结和分析以往的实验数据,对P因子做出了总结,得到了理论公式,对群桩水平承载力的研究起到了推动的作用。
In the pile foundation,when the pile group by is under horizontal force, if the pile group spacing is less than 8 times the pile diameter, pile group horizontal force is not equal to the sum of horizontal force of each pile, through test get smaller value of each pile horizontal force are often used in previous studies. P factor is a typical method of pile groups capacity reaction, but the theoretical research in this area is relatively small, the paper summarizes and analyzes the previous experimental data,makes a summary to the P factor, gets a theoretical formula, the study plays a catalytic role in the horizontal force of pile group.
