金茂大厦深基坑工程施工机理研究

The Study on the Mechanism of Ground Movement around the Deep Excavation of JIN-MAO Mansion

本文通过对金茂大厦深基坑施工监测数据进行分析,同时应用一维杆系有限元进行计算,并对它们进行比较分析,研究不同的施工方法在深基坑施工过程中对周围环境的影响,并定量分析深基坑的作用机理。

This paper analyzes the moniton data of deformation around the deep excavation of JIN-MAO mansion and calculates the deformation value by the use of bar Finite Element Method. Through the comparison of the measured and calculated values,the influence on the environ-ment due to the different construction methods in the course of deep excavation construction and the quantitative analysis of excavation deformation can be provided.
