| 本文以八仙山国家级自然保护区巡护及科考线路的地质灾害防治为目标，通过实地调查、地质环境条件分析、危岩稳定性定量计算及落石运动数值模拟等方法，系统研究了线路沿线地质灾害特征。结果表明:研究区地质灾害以崩塌为主，按线路走向分为南东侧和北西侧两个分布区，其中北西侧有崩塌隐患点 8处，南西侧有崩塌隐患点 4处；危岩稳定性评价显示部分隐患点处于欠稳定或不稳定状态，落石模拟揭示其运动距离、动能及弹跳高度差异显著，治理难度较大。基于此，提出以引导式防护网为主，结合主动防护网和被动防护网的柔性防护系统治理方案，该方案兼顾防灾减灾与生态保护，可为类似景区及保护区的地质灾害治理提供参考。 |

| This paper aims at the prevention and control of geological disasters along the patrol and scientificresearch routes in Baxianshan National Nature Reserve. Through methods such as field investigation，analysis of geological environmental conditions，quantitative calculation of dangerous rock stability，and numerical simulation of rockfall movement，it systematically studies the characteristics of geological disasters along the routes. The results show that geological disasters in the study area are dominated by collapses，which are divided into two distribution areas(southeast side and northwest side)according to the route direction. There are 8 potential col.lapse points on the northwest side and 4 potential collapse points on the southwest side. Evaluation of dangerous rock stability indicates that some potential hazard points are in an understable or unstable state. Rockfall simula.tion reveals that there are significant differences in their movement distance，kinetic energy，and bounce height， leading to great difficulty in treatment. Based on this，a treatment scheme of a flexible protection system mainly consisting of guided protective nets，combined with active protective nets and passive protective nets is proposed.This scheme takes into account both disaster prevention and mitigation as well as ecological protection，and can provide a reference for the management of geological disasters in similar scenic spots and protected areas. |
