| 摘 要： | 丹江口水利枢纽是南水北调中线重要的水源工程，初期工程大坝按地震烈度8度设防。根据区域地震活动资料以及空间和时间分布特征，从区域构造背景研究、近场区构造背景研究和工程场地断层活动性研究等3个层次出发，对工程场地的构造稳定性进行了评价，认为工程场地处于相对稳定的地块上，后期大坝加高工程可按地震烈度7度设防。

| Abstract: | Danjiangkou Hydro-junction is an important water source project in middle route of South-to-North Water Transfer Project.Its fortification intensity is determined at 8 degree at early days.In this paper,the author evaluates the tectonic stability of the engineering site based on 3 levels: regional tectonic setting,near-site tectonic setting,faulting at the engineering site.According to the above evaluation,the engineering site is believed to be located at relatively stable region,so the fortification intens... |
