摘要
本文基于对切坡失稳的边坡统计,通过简化边坡要素,对花岗岩区域自然坡度为35°、45°、55°的边坡进行模拟切坡,切坡高度为2.5m、5.0m、7.5m,切坡坡度为60°、70°、80°。模拟结果表明在对边坡进行切坡时,坡体稳定性均呈下降趋势,且随着切坡坡度、切坡高度的不断增大,其稳定性随切坡高度、坡度增大呈规律性地减小。采用具体实例进行了计算,验证了结论。这对花岗岩区域的边坡切坡具有重要的理论作用和工程意义。
In this paper,based on the statistics of slope unstabled by slope excavation,we simulated the slope stability in granite area with natural slope of 35°,45°and 55°with simplifying the slope elements.The cutting height is 2.5m,5.0m and 7.5m,and the cutting slope is 60°,70°and 80°respectively.The simulation results show that the stability of the slope tends to decline when the slope is cut,and the stability decreases regularly with the increase of slope height and slope height.The results are verified by a concrete example.It has important theoretical and engineering significance for slope cutting in granite area.
