【摘要】 地表沉降是地铁施工过程中最大的环境问题,当地层变形超过一定范围时,会严重危及邻近建筑物基础、邻近建筑物和地下管网的安全,引起一系列岩土环境问题。本文针对隧道穿越河流及桥基,对隧道自身的稳定性进行分析,并对穿越所造成的桥梁基础变形和位移的影响进行分析。更多还原

【Abstract】 Ground settlement is a significant environmental problem in metro construction.When the deformation exceeds a prescriptive range,a series of geotechnical environmental problems will come up with and the safety of buildings and underground pipelines adjacent to the tunnels is influenced by this phenomenon.In this paper,the stability of tunnels and the influence of crossing tunnel on bridge foundation deformation and displacements were analyzed.更多还原
