| 摘 要： | 近年来,随着我国基本建设的发展,越来越多的深基坑涉及承压水控制与降水引起的环境保护问题。特别是在建筑密集区,如何控制基坑降水引发的沉降成为研究的热点。在第三类深基坑降水中,将墙-井作用划分为4种模式:完全内包型、平齐型、部分内包型和完全外露型。基于墙-井作用改变水流方向、增加渗流路径和减小过水断面,利用地层渗透各向异性实现水位和沉降的控制。上海地铁9号线宜山路车站深基坑降水工程实践表明,采用墙-井第一模式控制坑外水位和地面沉降是可行的,可以作为类似深基坑降水工程的参考依据。

| Abstract: | Recently,with the development of construction in China,deep foundation pit has to face the problems of dewatering and subsidence.Especially in the region with dense building and protected building,it is most important to balance the dewatering project and induced subsidence.In the 3rd type seepage mode divided by the depth of concrete wall into aquifer,the interaction modes between concrete wall used as curtain and well filer tube can be divided into 4 modes:(1)well filter is inner covered completely by con... |
