weathering action meaning in Chinese
风化作用
Examples
- Concrete durability has been defined by the american concrete institute as its resistance to weathering action , chemical attack , abrasion and other degradation processes
美国混凝土学会对混凝土耐久性给出的定义是它抗击风化侵蚀、化学侵蚀、磨蚀和其他退化过程的能力。 - The study of cadmium concentration mechanisms under supergene weathering action can offer countermeasures in preventing cadmium pollution from the mining of phosphate rock
研究福元素在表生风化作用下的活化迁移沉淀富集机理可以为防治磷矿山开采中可能产生的镉污染提供对策。 - ( 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
本文研究结果为弱卸荷与弱风化大致对应、强卸荷与强风化大致对应； ( 6 )岩体是由组成它的岩石与缺陷赋存于一定环境场中的地质体，据此本文将岩体风化细划为岩石风化与结构面风化，并进而将表征岩体风化的指标相应地归结为三个方面来加以研究并应用于工程实践，这就是：对于岩石风化，主要为矿物的变异程度与风化岩石的物理力学性能研究：虽已认识到风化作用破坏了岩体完整性，但将该理论应用于岩体风化分带却不多见，本文即从浅表部位硬性结构面间距、条数、迹长、块度等随远离临空面的变化规律来研究岩体风化分带：不同风化、卸荷程度的岩体实际处于不同环境场中，弹性波速变化与特定环境场相对应，因而是反映岩体风化、卸荷的综合因素。 - 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。
