南水北调西线工程地质灾害初步研究

南水北调西线工程位于新构造活动强烈的青藏高原东北部，采用深埋长隧洞方案经巴颜喀拉山输水入黄河，工程区的主要地质灾害包括活动断层和地震、冻土冻害、高地应力及岩爆、地温异常、库区库坡变形等。其中，活动断层及地震是调水工程区的主要地质灾害，对主要地质灾害的特征和破坏形式进行了探讨，并提出了有关治理措施。

GEOLOGICAL HAZARDS ABOUT WEST-LINE PROJECT OF WATER DIVERSION FROM UPPER YANGTZE RIVER INTO UPPER YELLOW RIVER

Situated in the north east of the Tibet plateau where neo tectonic activity is violent, the west line project of water diversion from the upper Yangtze River into the upper Yellow River is to divert water by means of long deep lying tunnels cut across the Bayanhar mountain. The main geological hazards in the project region include the damages from active faults and earthquakes, destructiveness of frozen ground, high ground stress and rock blasting, geo temperature anomaly, and bank deformation in the reservoir. The most serious geological hazards are the fault activities and earthquakes. This paper discusses the major features and destructive forms caused by the hazards, and presents some measures to deal with these geological hazards.
