摘要
采用FLAC3D有限差分计算程序,考虑了管线沉降的土质、材质、直径、埋深、管隧水平间距等影响因素,建立了盾构隧道—土体—地下管线相互耦合的三维数值计算模型,模拟了盾构隧道开挖对平行地下管线沉降的影响。计算结果表明,管道周围的土质及其材质、直径、埋深、水平间距等因素对管线沉降的影响较为明显,在施工中应给予重点关注。
Based on FLAC^3D finite difference program, 3-D numerical analysis model dealing with shield tunnel, soils and buried pipeline was established to simulate the effect of shield tunnel construction on buried pipelines parallel to the tunnel, in which some influencing factors such as different soils, material properties, diameter, depth, horizontal distance and so on were considered. The results show that these factors have great influences on pipeline settlement, struction. should merit particular attention in construction.
