摘　　要：新沟河延伸拓浚工程常州市天宁区境内河道工程河道V标工程采用钢板桩和囊式扩大头锚索组合结构设计护岸,该工程位于常州市天宁区新沟河西岸,紧靠焦粮公路,公路沿线工厂和农村居民房屋众多,施工期间要求新沟河不断航、公路不断交通。做传统的护岸挡墙,河堤紧靠公路边、居民住地,原河岸线路长、场地狭小,土方不能大面积开挖,所以选用U型钢板桩做永久护岸,钢板桩顶部浇筑钢筋混凝土挡土墙加拉锚结构。钢板桩施工不能振动,为了避免周边建筑物振动影响,采用静压打桩机,减少干扰,缩短工期、施工质量得到保证。The river course V standard project of Xingou River extension dredging project in Tianning District,Changzhou City,adopted a combination structure bank protection type of steel sheet pile and anchor cable with capsule extension head.The project is located in the west bank of Xingou River,Tianning District,Changzhou City,close to Jiaoliang Road,along which there were many factories and rural residential houses.During the construction period,Xingou River was required to be continuously navigable and highways to be continuously trafficked.As a traditional revetment retaining wall,the embankment was close to the highway and the residential area,the original riverbank line was long and the site was narrow,the earthwork couldn't be excavated in a large area,therefore,the U-shaped steel sheet pile was chosen as the permanent revetment,and the steel sheet pile top was cast into the reinforced concrete retaining wall with anchor structure.Steel sheet pile construction could not be vibrated,in order to avoid the vibration of surrounding buildings,static pressure pile driver was adopted to reduce interference,shorten the construction period,and ensure the construction quality.
