| 摘 要： | 在深基础施工中,往往涉及到降水的问题,降水方案的选择及设计参数的确定是否合理,对工程质量、工期及工程造价等有很大影响。结合实例,论述了如何根据具体水文地质条件确定降水方案,如何利用现场降水井做抽水试验,对原有采用经验值确定的设计参数进行修改,以便达到降水目的,确保工程顺利进行。

| Abstract: | In construction of deep foundation, the dewatering problem is often related, whether or not the choice of dewatering plan and the determination of design parameters are rational that influence the quality,time and cost of engineering. Combining with some practical projects, how to determine the scheme of dewatering well in the light of specific hydrology condition and how to modify the original design parameters by experience according to the on-the-spot water pumping experiment in the dewatering well to guarantee the success of project are discussed. |
