深基坑坑内多管井降水涌水量计算的分析与思考

摘要

In diving in the stratum of deep foundation pit all use system,its section,propose more calculated precipitation has used a diving complete penetrateel well or big well method of non complete penetrateel well,the existing formula to calculate the principle for deviation,also exist on the calculation results of the differences.This paper firstly more inside casing well deep excavation of precipitation calculation formula according to the establishment of the Wells yield to comb,and secondly to a engineering calculation examples for its application,and finally some analysis,with reference.Supply%在潜水地层中的深基坑均采用系统的多管井降水,其涌水量计算却使用潜水完整井或非完整井大井法公式计算,这既存在原理上偏位,也存在计算结果的差异。通过工程计算实例,文章对深基坑内多管井降水按群井涌水量计算公式的建立给予梳理,说明其应用,并作分析。
