Abstract
In order to study the deformation law of enclosure structure of deep foundation pit in subway station in soil-rock compound stratum in Qingdao area, based on the foundation pit of Miaotou station of subway engineering, according to the site monitoring data, the deformation characteristics of pile body from excavation to bottom plate pouring and removing the steel support above the bottom plate are analyzed. The results show that the support mode of bored cast-in-place pile + inner support can effectively control the deformation of foundation pit. The erection of the third steel support has important influence on the location and size of maximum deep horizontal displacement of enclosure structure.关键词
