摘　　要：哈尔滨地铁1#线三期渤海路站-新疆大街站区间旁通道施工由于周边环境复杂、地层岩性变化大、岩性稳定性差、渗透性强、地下水含量丰富、补给充分,造成施工风险高,难度大。为解决地面加固和抽排地下水不便的问题,采用冻结法施工,该方法可以在冻结帷幕的保护下进行地下掘砌施工。Harbin subway line 1 phase 3 Bohai Road Station-Xinjiang Street Station intersection passage construction due to the influence of the surrounding complex environment, the lithology of the stratum varies greatly, the lithology stability is poor, the permeability is strong, the groundwater content is abundant, and the recharge is sufficient, the construction risk is high and difficult, High difficulty. In order to solve the problem of ground reinforcement and inconvenient drainage, the freezing method is used. This method can be used for underground excavation under the protection of freezing curtains.
