【摘要】 "三江"并流区地处印度板块与欧亚板块缝合带,现代构造应力作用强烈。受喜马拉雅运动影响,是第四纪以来抬升最强烈的地区之一,也是中国地质灾害最发育的地区之一,其中怒江、澜沧江、金沙江峡谷又是整个"三江"并流区斜坡变形破坏最强烈地区和地质灾害的集中发育区。怒江、澜沧江和金沙江上规划的大型水电站将面临现代构造应力影响、高边坡产生的水平应力影响,以及峡谷区崩塌、滑坡、泥石流、库区淤积、诱发地震等环境工程地质问题。解决这些重大环境工程地质问是该地区水电站建设的基本前提。更多还原

【Abstract】 Being located in the suture band of the Eurasian plate and the India plate,the modern structure stress is very strong in the area of the three river juxtaposition.The area is one of the most intense region of land upraising since Quaternary period,and it is also the one of the most growth region of geological hazard.The Nujiang gorge, the Lancang gorge and the Jinshajiang gorge are the centralizing growth areas of geological hazard in all the area of the three river juxtaposition.The hydropower stations that have been planed at the three rivers will be faced with the environment-engineering geology problems that include the modern structure stress,the stress from high slope, collapses,landslides,mud-rock flows,reservoir depositing,inducing earthquake etc.It is the premise of construction of the hydropower stations that these environment-engineering geology problems must be solved.更多还原
