摘要
珠江三角洲城际快速轨道交通广州至佛山段普君北路站—朝安站区间在管片处理冻结封水工程施工中,对冻结盐水温度、冻土温度、冻胀压力等方面进行了跟踪监测。通过对监测结果进行分析研究,获得了冻结盐水温度、冻土温度、冻胀压力的变化规律,在此基础上对冻结施工过程提出了建议。
Freezing method was applied to seal water leakage of shield segments on the section from Pujun North Road Station to Chao＇an Station on Guangzhou to Foshan inter-city rapid rail transit on Zhujiang River delta.During the construction,the temperatures of salty water and frozen soil,the frost heave pressures of soil were surveyed and monitored,and their variation regulations were examined.Based on these studies,some suggestions for freezing work are put forward,which can be severed as a guidline for similar projects.
