| 摘 要： | 对于大量中小型岩质边坡，由于地质结构简单、边界条件清晰，加之施工周期短，不可能也没有必要对其开展较大规模勘探工程、进行全面系统研究，因此，数值模拟技术成为这类边坡变形破坏分析及治理工程验证的首选手段之一。本文利用离散单元方法(DEM)分析了三峡水库某公路顺层岩质边坡开挖变形破坏机制及其演变过程，并对工程治理效果进行模拟研究。该方法节约了工程周期及造价，应成为中小型岩质边坡治理工程设计的辅助措施。

| Abstract: | For many medium and mini type lithologic slopes, with simple geology structure and clear boundary condition, numerical simulation technology is selected to analyze the slope failure and is a method of validating the control project, because the construction period is short and it's unnecessary to process a large scale exploration project. DEM is used to analyze the evolvement course of the excavation deformation of a road bedding lithologic slope in the Three Gorges reservoir region, and to simulate the effect of control project. DEM should be an assistant measure in designing control project of the lithologic slope, for it can save the cost and time. |
