  2. The main results are following : ( 1 ) the variation of clay / silt ratio can indicate the secondary clay action of dust depositions ; the variations of magnetic susceptibility and total fe content are inferred to be records of the changeable intensity of bio - pedogenesis ; the variations of sr content and rb / sr ratio can indicate bio - pedogenesis, dissolving and leaching action ; the content of total organic carbon ( toc ) can reflect variation of climate and vegetation during soil formation, it indicates the intensity of weathering and bio - pedogenesis ; the content variation of caco3 can show the intensity of dissolving - leaching action and secondary deposit, which was noted as pseudomycilia in pores and fissures in the sediment, so it can indicate the intensity bio - pedogenesis quite well. these proxy indexes also reflect obvious regional difference of pedogenic environment and the intensity bio - pedogenesis ; namely, secondary clay action, dissolving - leaching action and bio - pedogenesis are all much stronger in south than that in north

    實驗結果表明：粘粒粉沙比值能很好地指示粉塵堆積物的次生粘化作用；磁化率和全鐵很好地指示生物風化成壤作用； sr和rb sr比值能很好的指示生物風化成壤作用和淋溶作用；總有機碳（ toc ）含量的高低，在一定程度上反應了土壤發育過程中氣候和植被狀況的變化，指示著成壤過程中腐殖質化的程度； caco3含量的變化，可以反映了黃土古土壤形成時的風化成壤作用的強弱程度，指示成壤過程中的淋溶作用和次生碳酸鹽化作用；並且各指標所指示的成壤環境和成壤強度存在明顯的區域差異，即渭河流域土壤的生物風化成壤作用、次生粘化作用和淋溶作用均表現出南部強于北部。

  6. 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。
  7. ( 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於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，並進而將表徵巖體風化的指標相應地歸結為三個方面來加以研究並應用於工程實踐，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，但將該理論應用於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。
