武汉中心工程非落底式止水帷幕深基坑降水技术研究

Research on the Composite Dewatering Technology of Waterproof Curtain and Dewatering Deep Wells in Wuhan Center Project

以武汉中心深基坑工程降水为例,介绍了非落底式止水帷幕深基坑降水技术在武汉地区长江Ⅰ级阶地复杂地质条件下的应用与效果,分析了降水对土体稳定性、土体强度的提高作用和对支护结构的有利影响,最后对降水效果进行了评价。

Taking the dewatering of deep foundation excavation in Wuhan Center project as example, at the complicated geological conditions, the application effect of composite dewatering technology of waterproof curtain（the diagram walls isn＇t insert the impermeable layer）and dewatering deep wells used to reduce groundwater level is introduced. The favorable effects of dewatering on the soil stability, soil strength and enclosure structure are analyzed. The dewatering effect is estimated at the end.
