为了研究边坡工程中开挖角度对动态滑落的影响及评价整体安全稳定性,利用现代非接触测量技术,对辽宁境内庄盖高速(庄河-盖州)某边坡进行坡体结构面信息采集,并导入自主研发的GeoSMA-3D系统,建立该岩质边坡的三维裂隙空间实体模型,在工程不同开挖角度下搜索出边坡关键块体。在此基础上,利用二维数值流形法(NMM)程序,模拟不同开挖倾角下边坡断面动态失稳滑落过程,分析评价了工程边坡岩体的安全性与稳定性情况。
In order to study the influence of excavation angle on dynamic slipping in slope engineering and evaluate the overall safety and stability, the slope contact surface of a slope in Zhuanghe-Gaizhou (Zhuanghe-Gaizhou) in Liaoning Province was analyzed by using the modern non-contact measurement technique Collected and imported into the self-developed GeoSMA-3D system. The 3D solid model of the rock slope was established, and key blocks of the slope were searched under different excavation angles. On this basis, the two-dimensional numerical manifold method (NMM) was used to simulate the dynamic instability of slope sections under different excavation dip angles, and the safety and stability of engineering slope rock mass were analyzed and evaluated.
