| 摘 要： | 宝鸡市高速公路客运中心主楼基坑降水采用管井方案,原设计6个降水井,后又增加了2个降水井,但降水效果不甚理想,达不到降水设计要求,随进行了补充设计。根据场地地层情况及地下水条件,结合基坑开挖、降水现状和降水要求,依据现场抽水试验获得的水文地质参数,进行水文地质计算,确定出合适的集水井数量,并合理布置集水井和排水沟。通过集水明排与管井相结合的方法,节省了费用,取得了良好的降水效果。

| Abstract: | Adoption of tubewell scheme for water drawdown from the foundation of a main building in Baoji City obtained a poor result with 8 drawdown wells.Based on the stratigraphy,graoundwater conditions,drawdown conditions and requirements,hydrogeological coefficient obtained by pumping test in site,a supplementary design with combination of catchment,open ditch drainage and tubewell has made nicer effect in water drawdown. |
