Nevertheless , in these approaches the contact intethee are charactered sboly ed stiffeess k . and k . “ which is not perfect and rigorous in thc vitw of solid mechanics and rather rough for the description of the behavior of the idtfores . in collbet , taken as a contact problem , the principal chatrs of the idtcthees can be reflected : ( l ) the cbntact inifore is of shear strength which implies tha a generic pair of contact points on the inidse will displace coincidentally if the tangential fbrce at this point has not reahed the 1imit resistance , else , relative s1ide betwee the points will occur along the tangental direction . ( 2 ) no matter the relative slide occurs or not , the contact bodies cannot invade each other in any wise 本論文在對這兩種方法進行認真的分析后,說明它們對不連續面的描述并不合理,也無法反映出不連續面的主要力學特性,同時指出,將帶有不連續面的巖土工程問題作為接觸問題計算更為合理,它可將不連續面受力變形的主要特點反映出來,即: ( 1 )接觸面具有相應的“抗剪強度” ,即當接觸面上某一點處的切向應力小于該點處的抵抗強度時,點對共同變形;達到強度時,則沿切向發生相對滑動; ( 2 )在整個變形過程中,發生接觸的變形體不能相互侵入。
