摘要
顶管法施工因具有对周围环境影响小等优点而被广泛应用于市政管线上穿或下穿既有敏感构建物建设环境中,以某热力管道采用顶管穿越邻近桥梁、既有管线为例,通过MADIS-GTS有限元软件建立“桥梁-管道-土体”的三维模型,模拟顶管施工掘进地表、桥梁和周围土体的变形,分析顶管施工对桥梁的影响规律,并给出保障施工安全的建议。
The pipe jacking method is widely used in the construction environment of municipal pipelines passing through or under existing sensitive structures due to its advantages of minimal impact on the surrounding environment.This article takes a thermal pipeline passing through adjacent bridges and existing pipelines as an example,and establishes a three-dimensional model of"bridge pipeline soil"using MADIS-GTS finite element software to simulate the deformation of the excavation surface,bridge,existing pipeline,and surrounding soil during pipe jacking construction,analyze the impact of pipe jacking construction on bridges and existing pipelines,and provide suggestions to ensure construction safety.
