| 摘 要： | 普通地铁联络通道采用单侧隧道打孔冻结即可满足要求,对于复合地层中的超长联络通道,单侧隧道打孔冻结难以完成施工。通过对南京地铁二号线某超长联络通道(通道净长13.8m)冻结施工全过程的现场实测及研究,指出两侧隧道内分别打冻结孔分别设两个冻结站同时冻结完全可行。指出通过现场监测及数据分析,可以准确推算出不同土层中冻结壁发展情况和判断开挖时机。通过监测成果的分析得出了超长联络通道两隧道同时冻结施工过程中温度场、冻结壁发展、已有隧道变形等的相关规律,在此基础上,根据现场施工中发现的问题,提出相应的建议,可供类似工程参考。

| Abstract: | Making hole from one side can meet the requirements for construction of connecting aisle in normal subway tunnel.This method is not suitable for the site with complex soils and ultra-long channel aisle.In this paper,an ultra-long connected aisle (net length 13.8m) freezing from two sides is surveyed and researched.Through this research,it is pointed out that freezing from two sides to freeze the soil is entirely feasible,and the development of frozen wall in different soil layers through on-site monitoring ... |
