沈阳地铁二号线区间联络通道冷冻法施工设计论述

Discussion on Freezing Construction Design of Connecting Passage in Area of Shenyang Metro No.2 Line

随着城市化进程的加快,以地铁为主的城市轨道交通体系在我国正迅速发展,城市地铁以其安全、快捷、准时等特点越来越受到人们的青睐。地铁区间隧道在修建过程中,一般采用盾构法、矿山法、明挖法等进行施工,但由于隧道经过的土层及城市建(构)筑物情况比较复杂,上述的施工方法尤其矿山及明挖法往往需要辅助以降水、注浆、冷冻土层等施工措施。介绍了沈阳地铁二号线五里河站～奥体中心站区间隧道联络通道的冷冻法施工组织设计,有关经验可供相关专业人员参考。

With the speeding up of urbanization course,the urban rail traffic system taking the metros as mainly is fast been developing in China.The safe,quick and on-time characteristics of the urban metro are more and more favored by the people.The tunnel between the metros is generally constructed by the shield process,mine process and excavation process in the course of construction.The above construction processes especially the mine process and excavation process are sometimes required to assist the construction measures of dewatering,grouting and freezing soil layer because of the more complicated soil stratum and the urban buildings(structures) where the tunnel passes through.The article introduces the construction organization design of freezing process for the connecting passage of tunnel between Wulihe Station and Olympic Sports Center Station of Shenyang Metro No.2 Line.The relative experience can be referred for the professional members.
