【摘要】 本文对某大型水电枢纽工程场址的构造稳定性条件进行了研究,详细分析了区域地质构造背景、断层活动性、构造应力场特征以及地震活动性等问题。分析可知候选水电站坝址处于地壳构造活跃区内的一个相对稳定的地块,断层活动性较弱,区域构造地质作用相对较弱,完全可以通过工程措施予以控制,适宜于开展水利枢纽工程的建设。更多还原

【Abstract】 This paper has studied the tectonic stability of a dam site for a large-scale hydroelectric project,and analyzed the regional geological tectonic setting,activity of faults,historical earthquakes,tectonic stress fields of the project area.The analysis indicates that the dam site of the hydroelectric candidate project lies in a relatively stable block of the tectonically active region,where the fault movement is rather weak and so is the regional tectonic movement.Therefore,this site can be controlled by engineering measures and is suitable to the construction of the hydroelectric project.更多还原
