摘　　要：针对黄土峪隧道出口山坡的危岩问题,提出“清除+防护”的综合治理方案。在优化黄土峪隧道设计时,深入分析隧道出口处的不良地质现象以及特殊性岩土特性,制定“清除+防护”双管齐下的治理方案。在科学评估的基础上精准地清除不稳定的危岩,并实施综合防护措施,包括加固山体、设置防护网以及增加洞门墙的高度等,以提高整体稳定性。试验结果显示,在隧道的建设和运行期间,均未发生危石滚落现象,这表明该方案的应用效果良好,保障了公路隧道的施工与运营安全。In view of the dangerous rock problem at the exit slope of Huangtuyu tunnel,the comprehensive treatment plan of“removal+protection”is put forward.When optimizing the design of Huangtuyu tunnel,the bad geological phenomena and special rock and soil characteristics at the tunnel exit were deeply analyzed,and the treatment plan of“removal+protection”was formulated.On the basis of scientific assessment,the unstable dangerous rocks should be accurately removed,and comprehensive protective measures should be implemented,including strengthening the mountain,setting up protective nets and increasing the height of the cave door wall,so as to improve the overall stability.The test results show that during the construction and operation of the tunnel,there is no dangerous stone rolling phenomenon,which shows that the application effect of this scheme is good,and guarantees the construction and operation safety of the highway tunnel.
