摘要
对于大量中、小型岩质边坡,因地质结构简单、边界条件清楚,且施工周期较短、经费有限,不可能也没有必要对其开展较大规模勘探工作。而物理模型试验则周期较长、费用较高。因此,数值模拟技术可以替代模型试验,成为这类边坡变形破坏分析的首选手段之一。论文利用离散单元方法(DEM)分析了某公路陡倾角反倾岩质边坡开挖变形破坏机制及其演变过程,验证了教科书上该类边坡的机理,并在此基础上提出了边坡防治工程建议。该方法加深了对边坡变形的认识,节约了工程周期及造价,应成为中、小型岩质边坡研究的辅助措施。
For many medium and mini type lithologic slopes,with simple geology structure and clear boundary condition,numerical simuation technology is selected to analyze the slope failure instead of the model test,because the construction period is short and it′s unnecessary to process a large scale exploration project under a limited outlay condition.DEM is used to analyze the evolvement course of the excavation deformation of one road high anti\|dip angle lithologic bedding slope,and to validate the mechanism of this kind of slopes mentioned in the textbooks,on the basis of which the slope control project is suggested.DEM should be an assistant measure in researching medium and mini type lithologic slopes,for it deepens the cognition of the slope deformation and saves the cost and time
