上海地铁 2号线陆家嘴站至河南中路站区间上、下行隧道联络通道工程 ,采用水平冻结技术加固通道周围土层 ,在冻土帷幕保护下 ,开挖构筑通道。 从提供的地质资料、土工实验数据和土的物理力学性能指标来看 ,联络通道周围土层主要为淤泥质粘土 ,其孔隙比较大、含水丰富 ,在动
Shanghai Metro Line 2 Lujiazui station to Henan section of the middle and down the tunnel section of the tunnel project, the use of horizontal freezing technology to reinforce the channel around the soil, in the frozen soil curtain protection, excavation to build access. Judging from the geological data, geotechnical data and soil physical and mechanical properties provided, the soil around the communication channel is mainly silt clay with relatively large pores and rich water content.
