摘　　要：针对地下水水位较低、含水层又为黏土层的深基坑降水难题,提出了"管井-引渗井"相结合的联合降水方法,并结合郑州中部大观国际商贸中心工程实例,从降水方案设计、施工要点、质量控制等方面编制了一整套施工工艺,实践证明,该方法经济、可行,可在类似工程中推广。Aimed at the deep foundation pit precipitation problems of }ower groundwater level, and clay layer in aquifer, the combined precipitation method of ＂ pipe well-seepage well ＂ has been put forward and combined with the engineering practice of Zhengzhou Central Plaza International Trade Center Project, a whole set of construction technology has been prepared from the aspects of precipitation scheme design, construction key points, quality control and so on. Such practice has proved that this method is economic and feasible, and can be promoted in other similar projects.
