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 )歸納了表征巖體風化、卸荷程度的特征指標并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。 |

The essential cause inducing weather and unloading is distict difference between epigenetic - surface and deep condition . firstly , the dissertation introduces the background conditions that are the base of damsite granite rockmass weathring and unloading ; secondly , the mechanism of the rockmass weathering and unloading is probed into ; thirdly , different degree weathered zones and load - off zones are compartmentalized . tastly , right rockmass which meet the dambase demand is choosed . above - mentioned is the dissertation “ s technical course which is clearly from base research to application research . 本文以黃河拉西瓦水電站壩基花崗巖體為研究對象，從風化、卸荷發生的根本原因?巖體在地表與深部存在巨大環境差異為契入點，制定了從背景條件?機理研究?風化、卸荷分帶?壩基可利用巖體選取這樣一條從基礎研究到應用研究的較為明晰的技術路線。 |

( s ) weathering and unloading action which are the two main exogenous process is active in epigenetic - surface . so , although one is different with the other , they are associated with each other closely and are cntrolled by geostress and seepage fields . in fact , weak weathered zone corresponds to weak load - off one , strong weathered zone corresponds to strong load - off one in virtue of result of this dissertation . ( 6 ) rock mass is a geologic body which is composed of rock and structural plane . and under the condition of geostress . temperature and seepage fields , correspondingly . studying weathering should pay attation to the aspects of rock , structural plane and fields . according to this . the author subdivises rockmass weathering into rock weathering and structural weathering , ulteriorly , the dissertation studies rockmass weathering from three aspects as follows : ? ock weathering : aberrance degree of mineral and physical mechanical performance of weathered rock ; ? e have already knew that weathering action damage the integrity of rock mass , but few applies it to engineering practice . the dissertation is based on trend o 本文研究結果為弱卸荷與弱風化大致對應、強卸荷與強風化大致對應； ( 6 )巖體是由組成它的巖石與缺陷賦存于一定環境場中的地質體，據此本文將巖體風化細劃為巖石風化與結構面風化，并進而將表征巖體風化的指標相應地歸結為三個方面來加以研究并應用于工程實踐，這就是：對于巖石風化，主要為礦物的變異程度與風化巖石的物理力學性能研究：雖已認識到風化作用破壞了巖體完整性，但將該理論應用于巖體風化分帶卻不多見，本文即從淺表部位硬性結構面間距、條數、跡長、塊度等隨遠離臨空面的變化規律來研究巖體風化分帶：不同風化、卸荷程度的巖體實際處于不同環境場中，彈性波速變化與特定環境場相對應，因而是反映巖體風化、卸荷的綜合因素。 |
