摘　　要：介绍了环北部湾广西水资源配置工程玉林干线和玉林城区支线共槽段应急供水工程建设的主要内容,分析了工程的地质条件和施工技术难点。在输水管沟槽深基坑段软弱层厚度大,沿线地下水埋深浅,开挖易出现基底涌水、涌泥、涌砂、基坑坍塌等问题,采用了钢板桩支护与钢支撑的施工方案。论述了施工方法、控制措施以及“四新技术”的应用,取得了较好的经济技术效果。An introduction was made on main components of the emergency water supply project at the common trench section of Yulin trunk pipeline and Yulin urban branch pipeline of Guangxi Water Resources Allocation Proj⁃ect around Beibu Gulf.The geological conditions and construction difficulties of project were analyzed.The weak layer is thick and the groundwater is shallow in the deep trench foundation pit of pipeline,so problems such as wa⁃ter gushing,mud gushing,sand gushing and foundation pit collapse are prone to occur during excavation.Steel sheet pile support and steel bracing were adopted for construction.The author demonstrated the construction meth⁃od,control measures,the application of new technology,the good economic and technical effects.
