悬臂式排桩支护结构位移和弯矩的分析研究

摘要

Based on the cut-cover tunnel project in Shouyi Square of Wuhan, this paper aims to focus on cantilever piles supporting structures. Authors adopt the analytical method and numerical simulation, and calculate the deformation and stress of the cantilever piles supports in the cut-cover tunnel project in Shouyi Square of Wuhan. Meanwhile, the paper conducts a comparative analysis of the results and studies the pattern and characteristics of the displacement deformation and bending moments of the cantilever piles supporting structures in deep foundation excavation.%文章以武汉阅马场交通综合整治工程首义广场隧道工程为项目依托,以悬臂式排桩支护结构形式为主要研究目标,分别采用解析法和数值模拟法对武汉阅马场交通综合整治工程首义广场隧道工程中悬臂式排桩支护结构的位移和弯矩进行计算,并相互间进行结果的对比分析,研究分析了悬臂式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和特点.
