  4. Many studies had attempted to characterize chemical weathering process by focusing on geochemisty of river particulate and sediment. the sediment geochemistry may reflect and compare with the carbonates and silicates weathering degree by introducing the chemical index of alteration ( cia ) and new sediment index of variation ( siv ) and elemental molar abundance ratio of the sediment. the one main objective of this study would provide and compare the relative weathering intensities of silicates and carbonates with the different basins

    2沉積物地球化學與化學風化進程和機械剝蝕率化學風化指數與化學風化率屬于表徵化學風化作用意義不同的函數,前者為相對概念反映流域巖石在原巖基礎上己發生淋溶作用的深度,主要受到了氣候因子的深刻影響(中國流域沉積物化學風化指數由北到南呈有規則的遞增序列,氣候因子對風化進程的影響掩蓋了巖性的巨大差異) ,而化學風化率含義是指單位流域面積巖石風化淋溶產生的離子絕對總量。

  6. ( 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。
