摘　　要：U形板桩是一种新型的预应力钢筋混凝土预制构件,主要应用于河道、湖泊护岸治理、港口码头、城市基坑支护等工程。通过大沙河治理工程实例,分别对U形板桩护岸、灌注桩护岸、悬臂式挡墙护岸和生态砖护岸进行了分析对比,优选出技术可靠、安全稳定、经济合理的U形板桩护岸结构作为工程的处理方案。此类应用可以增强河岸美观效果并节约投资,在加快施工速度的同时减少对周边环境影响,可为类似工程提供参考。U-shaped sheet pile is a new type of prestressed reinforced concrete precast member,which is mainly used in river,lake revetment,port wharf,urban foundation pit support and other projects.Through an example of the Dasha River regulation project,this paper compares the advantages and disadvantages of U-shaped sheet pile revetment,cast-in-place pile revetment,cantilever retaining wall revetment and ecological brick revetment,and selects the technologically reliable,economical and reasonable U-shaped sheet pile revetment structure as the treatment scheme of this project.This scheme can not only enhance the river bank aesthetic effect and save investment,but also accelerate the construction speed and reduce the impact on the surrounding environment.It can provide reference for similar projects.
