摘要
通过对高原冻土区隧道特殊的工程、水文地质及环境条件分析认为,隧道施工对温度场、应力场和地下水流场产生较大的影响。在此基础上,提出采用超前地质预报、连通试验等技术,并结合昆仑山隧道、风火山隧道、达坂山隧道等工程实践,对高原冻土区隧道施工地下水防治措施进行了有益的探讨。
Through the Analysis of special engineering-geology, hydro-geology and environmental conditions of plateau permafrost zone tunnel, it was known that tunnel construction had great influence on temperature field, stress field and groundwater flow field. On this basis, geology prediction technology, connectivity tests, and other technology were proposed. Conjunction with engineering practice of kunlun mountains tunnel, fenghuoshan tunnel and dabanshan tunnel, beneficial discussion on tunnel constructing groundwater control measures in plateau permafrost zone were conducted.
