| 摘 要： | 毕机沟露天境界最终边坡高度达到510 m，其中山坡和凹陷露天各占一半。8~15线边坡形态复杂。为了确定经济合理的最终边坡角，应用FLAC3D研究了几个典型剖面的边坡稳定性，分别确定了各部分边坡的山坡、凹陷最终边坡角及台阶构成参数，并提出了各部分局部加固的参数。该方法适合研究岩质边坡的稳定性，易于技术可行、经济合理、简便实用地确定最终边坡角。

| Abstract: | At the boundary of the Bijigou open pit,the final height of the slope is 510 m,half of the slope and half of the depressed surface. Side slopes at line 8~15 is complex in shape. In order to determine the reasonable final slope angle,the slope stability of several typical sections was studied by FLAC3D ,and the slope angle and the step structure parameters were de-termined respectively. And the local reinforcement parameters for each part are put forward. This method is suitable for studying the stability of rock slope,and determining the final slope angle in feasible,economical and reasonable ways. |
