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 本文主要结论与认识为： ( 1 )对于岩体风化的研究从微观与宏观两方面入手，微观方面重视对矿物学、岩石学的研究，宏观方面，上升到岩体结构被改造的高度进行研究； ( 2 )归纳了表征岩体风化、卸荷程度的特征指标并提出了划分岩体风化、卸荷程度的几种方法； ( 3 )岩体结构控制着河谷浅表改造，但导致崩塌、滑坡、倾倒、松动等表生物理地质现象的直接原因乃是岩体的风化、卸荷。
