摘　　要：文中以S253远松线当阳市河溶大桥危桥改造工程为例,对新型桩-墙咬合圆形基坑支护施工技术进行探析,后续基坑变形监测显示,连续墙体的最大侧移为15.1 mm,旋喷桩的最大侧移为10.5 mm,周边的最大沉降量为25.4 mm,满足工程设计的要求。Taking the dangerous bridge reconstruction project of Dangyang Heyong Bridge of S253 Yuan Line as an example,this paper analyzes the construction technology of the new pile-wall biting circular foundation pit support.Through the subsequent foundation pit deformation detection,the maximum lateral displacement of the continuous wall is 15.1 mm,the maximum lateral displacement of the rotary spray pile is 10.5 mm,and the maximum settlement of the surrounding area is 25.4 mm.
