摘要
以济南城市轨道交通3号线二期工程川流站—向阳站区间联络通道施工为例,在地铁车站区间隧道内利用冻结方法加固地质围岩,使通道周围土体形成整体,形成具有高强度、封闭性较好的帷幕形式,并在冻结帷幕的有力保护下,采用隧道矿山暗挖方法进行通道的后续施工。该施工技术防水效果好,对周围环境影响小,为类似的城市地铁建设提供了参考经验。
This paper takes the construction of the contact channel between Chuanliu Station and Xiangyang Station in the PhaseⅡproject of Jinan Urban Rail Transit Line 3 as an example.Freezing method is used to strengthen the geological surrounding rock in the tunnel of the subway station,so that the soil around the channel is formed as a whole and the curtain form with high strength and good sealing is formed.Under the strong protection of the freezing curtain.The tunnel mining method is used to carry on the follow-up construction of the tunnel.The construction technology has good waterproof effect and little impact on the surrounding environment,which provides reference experience for similar urban subway construction.
