基坑底板施作后降水渗流对基坑变形影响规律OA
Influence Law of Precipitation Seepage on the Deformation of Foundation Pit after the Foundation Plate Construction
随着城市地下空间开发和建设需求的增加,基坑工程的开挖面积和开挖深度均越来越大,基坑降水对基坑变形和稳定性的影响越来越突出.为研究基坑在底板施作后不同降水深度条件下的变形特征,以北京城市副中心站综合交通枢纽基坑工程为例,运用有限元软件Midas GTS NX构建了详细的数值分析模型,系统性地探讨了底板施作后,不同降水条件下的基坑和地连墙变形特性.研究结果表明:降水深度对基坑顶部沉降变形影响显著,降水至基坑底部时导致的基坑沉降变形比不降水时的基坑沉降…查看全部>>
With the increasing demands for urban underground space development and construction,both the exca-vation area and depth of foundation pit projects have been steadily rising.The impact of precipitation on the defor-mation and stability of foundation pits has become increasingly prominent.In order to investigate the deformation characteristics of foundation pits under different precipitation depths after the bottom slab construction,the founda-tion pit …查看全部>>
