用莫尔-库仑准则判断软弱结构面的破坏及滑动问题

ON JUDGMENT OF THE DESTRUCTION AND SLIDE OF WEAK STRUCTURE SURFACES BY USTING THE MORH-COULOMB CRITERION

本文通过分析用莫尔-库仑准则判断软弱结构面的破坏及滑动问题,明确提出较为完善的判断依据和方法步骤,归纳出α值域法和应力比较法,并引出破坏度和滑动度等量,进而对软弱结构面的强度判断同岩体稳定性的关系作了综合分析。

Through analysing the destruction and slide of weak structure surfaces by means of the Morh -Coulomb criterion, this paper coearly advances a more perfact judgment basis and method steps, sums up the d - value district method and the stress comparing method, and leads to the destruction dcgre and the sliding degre and so on. In addition, it comprehensively analyses the relationship between the intensity judment of weak structure surfaces and the stability of rock body.
