| 摘 要： | 金川水电站地理位置处于不同构造单元的多组构造交汇复合地带,新生代以来构造活动、地震活动和水热活动均较强烈.为服务于大渡河金川水电工程规划建设的需要,作者对大渡河流域金川地区进行了地壳稳定性评价.依据地壳稳定性定量评价的原则和方法,将地壳稳定性划分为四个等级:稳定、次稳定、次不稳定和不稳定.综合各项研究资料确定定量评价指标,并采用模糊数学方法对地壳稳定性进行综合评价,结论表明,该地区适宜修建大型水电工程.

| Abstract: | Jinchuan hydropower station locates in the interjunction area of different tectonic units. The structure movements, earthquakes and hydrothermal activities are all relatively intensive. An assessment of regional crustal stability of Jinchuan region is given in order to service the planning of hydropower station in this article. The regional crustal stability is divided into four grades: stability, sub-stability, sub-instability and unstability according to the principals and methods of crustal stability assessment. A synthetic assessment regional crustal stability is given by using fuzzy mathematic methods. This assessment shows that a great water-electricity project can be constructed on the region. |
