The whole man - made rock slope reaches a maximum height of 600m. because of its complicated rock masses structure and epigenetic recreation process accompanying with the river ' s cutting down, the stability of high rock slopes is very distinctive in this site
樞紐區河谷峽窄，谷坡陡峻，自然邊坡坡高達1000餘米，開挖邊坡高達600 687m ，隨著邊坡的開挖和電站的施工，高邊坡的穩定性日趨顯著。 -
The main conclusions and cognitions are as follows : ( l ) rockmass weathering should be studied from either microcosmic and macrocosmic, microcosmic contain includes of mineralogy and of lithology, and in macrocosmic, weathering action damages integrality of rockmass, so studying rockmass structure can open out weathered degree of epigenetic - surface rockmass. ( 2 ] the dissertation sums up the characteristic indexes which can token weathered and unloaded degree, simultaneously, puts forth and summerizes several methods that classifies different weathered and relaxed zones of slope rockmass. ( 3 ) river valley epigenetic - surface reformation is controlled by rockmass structure, but weathering and unloading of rockmass is the direct cause which leads to different epigenetic - surface physical geology phenomena, for example, collapse, landslide, incline, dynam - relaxed and so on
本文主要結論與認識為： （ 1 ）對于巖體風化的研究從微觀與宏觀兩方面入手，微觀方面重視對礦物學、巖石學的研究，宏觀方面，上升到巖體結構被改造的高度進行研究； （ 2 ）歸納了表徵巖體風化、卸荷程度的特徵指標並提出了劃分巖體風化、卸荷程度的幾種方法； （ 3 ）巖體結構控制著河谷淺表改造，但導致崩塌、滑坡、傾倒、松動等表生物理地質現象的直接原因乃是巖體的風化、卸荷。
