基坑开挖会对邻近管线造成附加的变形和受力,如果控制不当,甚至会引起管线的破裂,因此对复杂条件下的基坑围护结构的设计计算也越来越为业内人士所重视。本文通过某一紧邻重要保护管线的基坑围护设计,运用理论知识及数值模拟软件,研究分析基坑开挖对周边管线的影响,为今后类似工程提供参照。
Excavation of the foundation pit will cause additional deformation and stress on the adjacent pipeline. If the control is inappropriate, it may even lead to the rupture of the pipeline. Therefore, the design and calculation of the foundation pit retaining structure under complex conditions is more and more valued by the people in the industry . In this paper, the influence of excavation on the surrounding pipeline is researched and analyzed through theoretical analysis and numerical simulation software through the design of the foundation pit surrounding an important protection pipeline, which provides a reference for similar projects in the future.
