摘要
本文提出了一种分层土中的单桩分析法,该法以边界积分法为基础,以Mindlin应力解作为初始基本解,引入沉降调正系数,对初始基本解进行不断的修正,使分析适于各种非均匀土情况。与已有的理论解和试验结果进行了比较,结果基本一致。根据数拾根桩的试验资料,讨论了地基土参数的取值问题,给出了简单的土模量取值方法。
An analysis approach of a single pile in layered soil is presented based on the Mindlin＇s stress solution by BEM. An iterative modification to the solution is developed for nonhomogeneous medium in which a pile was embedded. Detailed comparison is made between the approach and other accurate methods as well as model and field pile tests. Back-computation of the soil parameters is carried out from test results of over sixty piles in Shanghai and a simple formula of the soil modulus used in predicting settlement of piles is given.
