摘要
结合上海地铁四号线修复工程,采用基于"一线总线"的冻结法温度监测系统进行现场实时监测,并依据监测数据,判别了冻结管是否漏盐水以及完好隧道段冻土壁的封水效果,得出了冻土壁温度场形成规律和积极冻结期结束时间,并分析了各施工工序对冻结壁的温度影响。
Combined with the recovering collapse tunnel in Shanghai Metro,the frozen soil temperature was real-time monitored by a system based on ＂1-wire Bus＂.According to monitored number,the situation of leaking brine in freeze-tubes and watertight result outside the completed tunnel was judged.The temperature field character of the frozen soil,the end time of active freezing,and the variation of temperature affected by the excavation were analyzed.
