摘要
以武汉阅马场首义广场隧道工程为依托,以排桩+钢支撑支护结构为主要研究目标,采用解析法和数值模拟法对该工程中的排桩+钢支撑支护结构的位移变形和弯矩进行模拟计算,并与实测位移进行比较。对比分析计算结果,研究分析了排桩+钢支撑支护结构在基坑开挖过程中桩身侧向位移和受力弯矩的分布规律及特点。
Based on the cut-cover tunnel project in Shouyi Square of Wuhan, focusing on supports structure of row piles and steel supports, this paper adopts the analytical method and numerical simulation to calculate the deformation and stress of the supports structure in the project. Meanwhile, this paper conducts a comparative analysis of the results and concludes the pattern and characteristics of the displacement deformation and bending moments of the supports structures in deep foundation excavation.
