【摘要】 在岩石力学中, 摩擦的研究是非常重要的, 并逐渐形成了与岩石有关的表面接触力学。本文在自然状态和接触面掺泥两种情况下, 进行了砂岩、泥岩破碎面及其互层接触的摩擦试验。结果表明: 在接触面掺泥时, 抗剪强度的粘聚力和内摩擦角都有不同程度的降低, 其中粘聚力下降明显, 并且剪应力与摩擦位移关系曲线有明显不同, 而且粘滑现象明显渐弱。更多还原

【Abstract】 It is important of friction te in rock mechanics,and formatting a mechanics course about contact surface.With natural surface and blended mud surface,friction properties of sandone,mudones broken surface is te.Its is show that the rength of surface blended mud is reduced.It is different of the curves of ress-displacement of natural surface and bended mud surface,and the phenomena of mucosity is weakened.更多还原
