基坑工程地下一、二层交界区支护体系的设计与分析

Design and analysis of bracing system for junction of basement floor No. 1 and No. 2 of a foundation pit

摘要: 结合某项目基坑工程设计实例,介绍了一种基坑工程地下一、二层交界区支护体系的设计分析方法。同时,选用岩土工程有限元程序Z_SOIL.PC 2013,运用三维数值分析方法对本方法进行建模计算,并将计算结果与实测数据加以比较分析,证明了该设计方法的可行性,最后,针对本工程的实践情况,总结了一些工程体会。

Abstract: According to the design example of a foundation pit, a method for design and analysis of bracing system for the junction of basement floor No. 1 and No. 2 is introduced. Meanwhile, the geotechnical FEM software Z_SOIL.PC 2013 is adopted to calculate the model by using 3D numerical analysis method. The results of the numerical analysis are compared with the measured ones, indicating the feasibility of the proposed design method. Finally, some experience of the project is summarized.
