摘 要: 以沈阳地铁某车站为工程背景,利用FLAC3D建立钢管顶进过程的数值模型,对钢管顶进过程中提供反力的结构进行分析。结果表明:钢管顶进过程中,提供反力的结构最大水平方向位移0.42 mm,且位移影响范围很小,混凝土受力均在允许范围内,满足顶管施工要求。 The model of pipe jacking based on subway station is established using FLAC^3D to analysis the deformation and force of reaction structure. The results indicate that the maximum horizontal displacement of structure provided counterforce is 0. 42 mm, and the range of displacement is very small, force is within the allowable range on concrete, it meets construction requirements.
