摘    要:顶管施工过程中地表埋深一般较浅,而且常穿越或临近既有建筑物及道路桥梁,从而对既有结构的稳定性产生不确定的影响.鉴于此,通过数值模拟顶管施工过程,分析了开挖过程中周围土体变形、变化情况,可为相关施工提供参考.

关 键 词:顶管施工  既有结构  稳定性  数值模拟

Abstract:The buried depth of the earth's surface is shallow during pipe jacking construction, and the construction process often goes through or near the buildings, roads and bridges, which brings uncertain effect on the stability of the structure. Given this, based on the numerical simulation of pipe jacking construction process, this paper analyzes the deformation and change of surrounding soil during the excavation process, which can provide reference for relevant construction.
Keywords:pipe jacking construction  existing structure  stability  numerical simulation
