摘　　要：长白山南景区地质灾害频发,尤其是景区公路沿线边坡上部的危岩体较为发育,易发生崩塌落石灾害,对过往游客生命财产安全造成威胁。为保证长白山南景区顺利运营,拟修建棚洞对景区鸭绿江大峡谷段公路进行防护。在棚洞设计满足基本防护功能的同时融入长白山地区建筑风格的特征,使其与周围环境融为一体。并通过冲击数值模拟验算验证了设计棚洞在危岩体冲击下的稳定性,说明了该棚洞设计方案安全可行。Geological disasters occur frequently in the south scenic area of Changbai Mountain,especially the dan⁃gerous rock masses on the upper part of the slope along the highway in the scenic area are well developed,which can lead to landslide and rockfall disasters,posing a threat to the safety of life and property of tourists.In order to en⁃sure the smooth operation of the south scenic area of Changbai Mountain,it is planned to build a shed tunnel to pro⁃tect the highway in the Grand Canyon section of Yalu River.The shed tunnel is designed in such a way that it has both the basic protection functions and the architectural characteristics in the Changbai Mountain area,so as to be integrated into the surrounding environment.Besides,the stability of the designed shed tunnel under the impact of dangerous rock mass is verified through the impact numerical simulation calculation,indicating that the design scheme of the shed tunnel is safe and feasible.
