摘要
介绍了沈阳地铁2号线五里河站—奥体中心站区间隧道联络通道的冷冻法施工设计。根据区间隧道联络通道所处的地质条件,提出冷冻施工方案。着重介绍了施工流程,冻结法加固土体,制冷设计,冻结孔、测温孔的布置方案,以及开挖构筑施工中的注意事项等。
Taking Shenyang metro L2 for example,its section contact tunnel(from Wulihe Station to Aoti Center Station) is designed and constructed by freezing method.According to the geological conditions,the freezing construction plan is proposed with focusing on construction procedures,strengthening soil body by freezing method,layout plans of freezing hole & thermometer hole and the cautions for excavation & construction.
