摘　　要：以花石沟隧道出口边坡为依托,利用FLAC3D软件中强度折减法对其稳定性进行计算和分析,并通过模拟不同治理方法的边坡状态,最终找出合理适用的治理方法。研究结果表明:采用锚杆喷浆加固边坡,取得了较好效果。Depending on the slope at the exit of Huashigou Tunnel, the stability was calculated and analyzed by the strength reduction method based on the software FLAC3D; in addition, through simulating the slope state under different treatments, the reasonable and appropriate treatment measures were proposed. The study result shows that bolt-shotcrete has good effect on slope reinforcement.
