武汉某工程超深基坑降水设计与技术应用

Dewatering Design and Technology Application of Super Deep Foundation Excavation in a Project in Wuhan

针对武汉地区沿长江流域的复杂水文地质条件,以沿江一处在建工程项目为例,结合该工程的实际特点:含水层厚度大、地下水位高、含水量丰富、临近长江处长江Ⅰ级阶地超深基坑、基坑降水易出现安全事故等,详细介绍了该工程超深基坑降水设计及施工经验,探讨了临江地区承压水超深基坑降水关键技术,并提出了基坑降水远程自动化监控系统创新。

In view of the complex hydrogeological conditions in Wuhan region along the Yangtze River Basin,the paper takes a project under construction along the river as an example,combining actual characteristics of the project: large thickness of aquifer and high underground water level,rich water content,adjacent to the super deep foundation excavation of the Yangtze River Ⅰ level terrace,and frequent occurrence of safety accidents about foundation excavation dewatering,introduces the project deep foundation excavation dewatering design and construction experience in detail,discusses the key technology of super deep foundation excavation dewatering of confined water along the riverfront,and puts forward the remote automatic monitoring system innovation about foundation excavation dewatering.
