辐射井降水技术在大面积基坑工程中的应用

Application of Radiate Dewatering Well in Large-scale Foundation Pit Engineering

摘要:

辐射井降水技术适用于各种地层，单井控制降水面积大，对疏干含水层有特效，与其它工序干扰小，占地面积少，管理方便，是大面积基坑降水的有效方法。通过中国电影博物馆基坑降水实例,介绍在大面积基坑工程中辐射井降水技术的设计、施工及降水效果。

Abstract:

Dewatering by radiate well can be applied in various formations with large scale of dewatering by a single well; it is an effective dewatering method with advances of fewer disturbances to construction, less area and convenient management. Based on the dewatering case of foundation pit of China National Film Museum, the design, construction and result of dewatering for large-scale foundation pit were introduced in this paper.
