砂井地基固结参数反分析研究

以Biot固结理论为基础,根据砂井地基的平面应变等效方法,结合优化方法,建立了考虑加载过程的软土地基参数反分析方法及地基变形预测方法,得到了适用于软土地基固结的正反分析程序,并将该方法用于工程实例进行分析、验证,得到了较为满意的分析结果。

Study on Back Analysis for Consolidation Parameters of Sand Drained Ground

Based on Biot consolidation theory, this paper, by means of equivalentplain stain of sand drained ground, together with optimization method, established the back analysis method for soft foundation parameters, which takes loading process into consideration, and the method predicting foundation deformation and obtained the positive and negative analysis procedures applicable to soft foundation consolidation. The method was used in project cases for analysis and verification, and got satisfied results.
