摘要:
为保证某临近地铁车站深基坑在施工过程中安全，采用数值模拟的方法分析了该基坑临近地铁车站一侧桩锚联合支 护结构在施工过程中的变形情况，并对其进行稳定性分析．分析表明：临近地铁车站一侧基坑支护结构最大侧移发生在离坑顶约7 m处，最大侧移为13.4 mm；最大地表沉降出现在距离基坑边约4m处，最大沉降量为8.81 mm；桩锚联合支护结构具有较好的稳定性，能够有效控制基坑在开挖过程中变形，工程深基坑的开挖没有影响到地铁车站安全．
Abstract:
In order to ensure safety of deep foundation pit nearby the subway station in the construction process, the deformation of pile-anchor retaining structure nearby the subway station in the construction process is analyzed by numerical simulation method, and its stability is also analyzed. The study showed that the maximum lateral displacement of pit-retaining structure occurs at about 7m away from the top of the pit, and maximum lateral displacement is 13.4mmAnd the maximum surface subsidence occurs at about 4m away from the pit, and the largest settlement is 8.81mm. the pile-anchor retaining structure has good stability, and can effectively control the deformation of the pit during excavation. This background engineering deep foundation excavation does not affect the safety of the subway station.
