摘要
明挖法地铁车站是城市轨道交通工程中比较常见的地铁车站形式,传统敞开式明挖基坑施工造成的扬尘与噪声不易控制,对周边环境的影响较大。明挖基坑防尘隔离棚作为封闭式明挖车站施工的创新,满足了北京地区日益严峻的环保要求。结合具体工程实例,对较大规模的明挖基坑防尘隔离棚的结构形式进行了技术与经济比较及造价分析,为今后类似工程提供一定的借鉴与参考。
Open-cut metro station is one common form of the metro station in the urban rail transit project.It is not easy to control the dust and noise caused by traditional open-cut foundation pit construction,which has a significant impact on the surrounding environment.As an innovation of closed open-cut station construction,the dust-proof isolation shed of open-cut foundation pit meets the increasingly strict requirements on environmental protection in Beijing.Referring to the project case in practice,this study analyses the technical and economic comparison and cost on the structure for mation in dust-proof isolation shed of large-scale open excavation foundation pit,which provides significant implica tions and references for similar projects in the future.
