摘要

在深港西部通道深圳侧接线工程填海区基坑工程中，开挖与回填过程中的不均匀沉降问题是该工程设计与施工中的关键技术难题之一。在综合考虑复杂地质条件、结构自身的约束条件以及结构与土体之间相互作用的基础上，采用非线性有限元方法对基坑的开挖与回填过程进行数值分析，研究其变形特性与规律，为工程开挖与回填设计提供重要参考的同时，也验证了该数值模拟方法的合理可行性。

Abstract

Excavation and earth filling of foundation fundation pit under complicated geological conditions is one of the important problems in the underground engineering field. By considering complicated geological conditions

constrained conditions of structure and the interaction between structure and soils

this paper concerns about the nonlinear FEM numerical calculation of excavation and earth-filling of foundation pit by combining with the Western Long Tunnel Construction Project from Shenzhen to Hongkong. The characteristics and regularities of the calculated settlements in the excavation and earth-filling process are obtained. The results can be used as an important reference to the design and construction of engineering.
