摘要

摘要: 基于荷载传递法，提出了船坞坞室基坑开挖卸荷后单桩竖向荷载位移关系非线性简化分析方法。计算模型考虑了桩土相互作用的非线性特性和土体超固结效应对单桩承载力的影响，比较符合船坞底板桩基实际工作性状。采用有限差分法对单桩进行求解，计算结果与有限元计算值进行对比分析，验证了本文方法的正确性，可应用于实际工程问题的分析。

Abstract: The load transfer method is adopted to obtain the simplified nonlinear analysis of settlement of vertically loaded single pile in dock pits after excavation. Considering the overconsolidation effect and nonlinear interaction between piles and soils, the theoretical model agrees with the fact quite well. The governing equation of single pile is solved by the finite difference method. The results of the finite element are compared with the calculated results, which proves the predictive capacity of the proposed method.
