金沙江虎跳峡河段岸坡变形破坏的相关动力因子研究
|
摘要
河谷岸坡的变形与破坏是地球内外动力耦合作用的结果,并且每一种动力地质作用对于岸坡变形失稳的贡献程度不同,造成岸坡变形破坏频率和规模的空间差异。金沙江虎跳峡地区内、外动力地质作用十分显著,岸坡变形破坏体的空间分布具有鲜明的地段性。本文采用定性与定量相结合的效果测度分析方法,对虎跳峡河段岸坡变形破坏密度与相关动力因子进行关联度量化分析,从而确定了影响岸坡稳定的关键性动力因子,可为水电开发中的岸坡灾害成因类型划分、危险性评价、灾害治理和工程规划设计等提供科学依据。
It is a rather well-known fact that bank-slope deformation and failure result from the coupling of Earth's endogenic and exogenic geological processes,in which different dynamic-force factor has a different correlation to the evolution of bank-slope.In Tiger Leaping-gorge region,endogenic and exogenic geological processes are very prominent,and in different reaches the deformed and failured masses develop dissimilarly.The correlated degree of the density of deformed and failured masses and correlative dynamic force factors in Tiger-Leaping Gorge Reach are analyzed by effect measure analysis method which combines qualitative and quantitative analysis,and the key dynamic factors of bank-slope stability are established,which can provided the scientific information for origin division,evaluation,prevention of geological hazards and project planning.
