【摘要】 结合上海地铁联络通道的冻结施工,介绍了联络通道和泵站合并建设模式下的冻土帷幕结构设计与水平冻结工艺,以及控制冻胀融沉的措施-强制解冻融沉注浆。对土体温度和地表变形等相关信息进行了监测,并对实测结果进行了分析。为今后联络通道冻结法施工提供了一定的参考。更多还原

【Abstract】 Taking frozen construction of a thoroughfare of Shanghai Metro into account,the paper introduces the design of frozen soil structure and level freezing technology in the connected aisle project where this aisle and the pumping station are built together,and the measure of controlling frost heaving and thaw collapse by foroed-thawing and grouting.The soil temperatures and ground surface deformation and associated information were monitored during the construction and the results measured were analyzed.The conculusion can be referred by future freezing method for construction of side channels.更多还原
