商务大厦深基坑降水设计

Dewatering Design for Deep Foundation Pit of Commercial Building

以某大厦基坑降水实践,介绍在上层滞水水位较低,地层渗透系数大的水文地质条件下,基坑降水的参数选取、方案设计等过程,并在此基础上进行了抽水试验,结果表明,此项工程降水设计合理,参数选择正确,对同类工程有很强的借鉴意义。

In the paper,it is introduced the process of selecting parameters and designing plans for dewatering under the hydrogeological conditions of lower upstream backwater level and big coefficient of permeability for stratum,as well as the pumping test is carried out.The results show that the dewatering design of the project is reasonable and the selection of parameters is right,which could provide significant references to similar projects.
