摘要:
针对西安地铁车站深基坑地表沉降及支护桩侧向变形性状开展了统计分析．分析表明：西安地铁车站深基坑地表沉降集中于0～12 mm 范围，支护桩侧向变形集中于0～8 mm，两者均小于其它地区的统计值．基坑地表沉降表现为“凹槽形”模式，距离坑壁10～15 m内地表沉降值最大，距坑壁30 m以外沉降较小．基坑支护桩变形表现为“中凸形”或“悬臂形”两种变形模式，除个别测点支护桩顶部向基坑外变形外，其余均向基坑内变形，其中，“中凸形”模式变形的支护桩距地表5～15 m内变形最大，“悬臂形”模式支护桩顶变形最大，并随深度增加而逐渐减小．
Abstract:
A statistic analysis of the properties of the ground settlement and the lateral deformation of soldier pile of the deep excavation in Xi ’an metro station is performed. The result shows that: Ground settlement of the deep excavation in Xi’an metro station mainly ranges from 0 mm to 12 mm, while the lateral deformation of soldier pile mainly ranges from 0 mm to 8 mm, both of which are smaller than that of other areas. The shape of the foundation ground settlement is groove-like , which means the ground settlement of the area within 10m to 15m from the foundation pit wall is the biggest ,while that of the area 30 m away the foundation pit wall is smaller. The shape of the lateral deformation of soldier pile is like convex or cantilever. Deformation direction of most soldier pile is towards the foundation pit except for a very few piles are on the biggest deformation of the convex shape takes at the pile 5 m to 15 m below ground, while the biggest deformation of the cantilever shape is on the top of the pile, and the deformation decrease with the increase of the distance to the top of the pile.
