摘　　要：滇中引水工程在金沙江石鼓段右岸无坝引水,经石鼓泵站提水,由输水总干渠工程向各受水区分水。工程总体布置由水源工程和输水工程两大部分组成。水源工程由引水渠(兼沉沙池)、进水塔、进水流道、地下泵站、出水隧洞、出水池和地面开关站等建筑物组成。穿冲江河箱涵工程是进水流道的主要组成部分,通过分析箱涵深基坑明挖施工降水技术方案,提炼总结出一些降水实施过程中的要点。The general layout of the project is composed of water source project and water conveyance project.Water source engineering consists of diversion canal,intake tower,intake channel,underground pump station,outlet tunnel,outlet pool and ground switch station.The box culvert project crossing Chongjiang River is the main part of the intake channel.Through analysis of the technical scheme for dewatering during open excavation of deep foundation pit of box culvert,some key points in dewatering implementation process are extracted and summarized.
