摘　　要：基坑围护方案设计作为水利工程建设的关键技术之一,在保证基坑内安全稳定的同时,控制基坑开挖对周边环境的影响。本文结合走马塘江边泵站工程的基坑围护方案,对其进行了描述,并对泵房及交通桥段采用的“灌注桩+对撑”围护结构,分析开挖工况和计算结果,为类似基坑围护设计提供参考。As one of the key technologies in hydraulic engineering construction,the design of foundation pit enclosure scheme can not only ensure the safety and stability of the foundation pit,but also control the influence of foundation pit excavation on the surrounding environment.This paper describes the foundation pit enclosure scheme of Zoumatang Pump Station Project by river,and analyzes the excavation conditions and calculation results of the"grouting pile+support"enclosure structure used in the pump house and the traffic bridge section,so as to provide reference for similar foundation pit enclosure design.
