| 摘 要： | 研究岩体结构面的力学性质对评价岩体工程的稳定性具有重要意义.根据Patton剪胀公式并结合ABAQUS软件中接触面滑动判定法则推导出定法向刚度下规则锯齿刚性结构面的剪胀公式,同时建立了相应的数值模型,两者计算结果一致.按锯齿倾角和法向刚度建立了16种结构面剪切模型,对各种模型的剪切位移曲线进行了分析,提出了一个参数:变...

| Abstract: | It is important to study the mechanical properties of rock joint to evaluate the stability of rock mass engineering.According to Patton shear dilatancy formula and contact surface sliding judgement rule with ABAQUS software,the shear dilatancy formula of regular serrated rigid joint subjected to constant normal stiffness is derived and the corresponding numerical models are established.The calculation results of numerical models and theoretical formula are in agreement.The 16 different shear models are esta... |
