借助于所研究的方法进行变分计算确定,当裂隙倾角较平缓(δ<40°)时,台阶高度对台阶坡面极限角没有显著影响;当裂隙倾角较陡时,台阶高度增加到2倍时,其允
By means of the variational calculation method, the step height has no significant effect on the limit angle of the step slope when the cleat angle is relatively flat (δ <40 °). When the cleat angle is steeper, the step height increases to 2 times When, it allows
