含泥卵石层中基坑降水的设计

摘要

以福州市某降水工程为例,根据含泥卵石层的水文地质特点,通过方案比选、降水设计计算、降水施工效果等方面进行阐述,最终确定坑内管井降水是可行的,从而为该地区同类工程的设计积累了宝贵的经验.%Taking a project as an example of precipitation in Fuzhou, according to hydrogeological characteristics of gravel layers with mud, through the comparison and selection of design and calculation of precipitation, and precipitation construction effects, the inside tube well precipitation is determined to be feasible finally.So it can provide valuable experience for design of similar projects in same area.
