(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(jié)果為弱卸荷與弱風(fēng)化大致對(duì)應(yīng)、強(qiáng)卸荷與強(qiáng)風(fēng)化大致對(duì)應(yīng);(6)巖體是由組成它的巖石與缺陷賦存于一定環(huán)境場(chǎng)中的地質(zhì)體,據(jù)此本文將巖體風(fēng)化細(xì)劃為巖石風(fēng)化與結(jié)構(gòu)面風(fēng)化,并進(jìn)而將表征巖體風(fēng)化的指標(biāo)相應(yīng)地歸結(jié)為三個(gè)方面來(lái)加以研究并應(yīng)用于工程實(shí)踐,這就是:對(duì)于巖石風(fēng)化,主要為礦物的變異程度與風(fēng)化巖石的物理力學(xué)性能研究:雖已認(rèn)識(shí)到風(fēng)化作用破壞了巖體完整性,但將該理論應(yīng)用于巖體風(fēng)化分帶卻不多見(jiàn),本文即從淺表部位硬性結(jié)構(gòu)面間距、條數(shù)、跡長(zhǎng)、塊度等隨遠(yuǎn)離臨空面的變化規(guī)律來(lái)研究巖體風(fēng)化分帶:不同風(fēng)化、卸荷程度的巖體實(shí)際處于不同環(huán)境場(chǎng)中,彈性波速變化與特定環(huán)境場(chǎng)相對(duì)應(yīng),因而是反映巖體風(fēng)化、卸荷的綜合因素。
