摘要
结合川气东送管道工程武汉长江盾构穿越工程冻结法修复隧道施工,对冻结盐水温度、冻土温度、地下水文孔水位等方面进行跟踪监测。通过对监测结果进行分析研究,获得冻结盐水温度、冻土温度、水文孔水位等变化规律,在此基础上提出隧道修复冻结施工的建议。
The application of the freezing method in the recovery of the shield-bored Yangtze River crossing tunnel in Wuhan on Sichuan Gas East Transmission Pipeline project is presented.During the freezing,the temperatures of the brine water,frozen soil and the water levels in the hydrological holes are monitored and the variation rules of the brine water temperatures,the frozen soil temperatures and the water levels in the hydrological holes are obtained.Finally,recommendations are made for the freezing construction of the tunnel on basis of the study results.
