摘　　要：通过紧邻地铁的深基坑工程项目实际运用,论证了自动轴力伺服系统在深基坑开挖过程中的效果。工程选取了多个测斜点,对基坑施工过程中的围护结构深层水平位移实时监测数据进行了分析,结果显示:较之传统混凝土支撑,自动轴力伺服系统施工速度快,约束效果好,并在一定程度上能起到变形补偿的作用。Through the practical application of the deep foundation pit project adjacent to subway, the effect of automatic axle force servo system in the process of deep foundation pit excavation is demonstrated. Several inclination survey points are selected to analyze the real-time monitoring data of deep horizontal displacement of retaining structure during foundation pit construction. The results indicate that, compared with the traditional concrete support, the construction speed of the automatic axle force servo system is faster, has good restraint effect and can play the role of deformation compensation to a certain extent.
