摘　　要：山区公路建设和运维中,危岩落石对道路边坡的稳定性破坏较大,边坡通常会因落石冲击力产生形变。依据实际工程案例,利用RockFall Analysis进行落石运动仿真,选择落石运动轨迹、落点、弹跳高度和冲击能量等作为主要风险评估和控制指标,分析不同场景下落石现象对道路和边坡的损害程度,提出柔性防护和柔性棚洞相结合的病害处治措施,基于此进行边坡综合防护系统和柔性棚洞结构设计。研究结果表明,依据实际工况和落石仿真分析设计的道路边坡柔性棚洞综合防护系统有利于边坡维稳。In the construction and operation and maintenance of mountainous highways,the stability of road slopes is greatly damaged by the disease phenomena such as rockfall,and the slopes usually deform due to the impact force of rockfall.This study is based on actual engineering cases,using RockFall Analysis for rockfall simulation,selecting the trajectory of rockfall,fall point,bounce height and impact energy as the main risk assessment and control indexes,analyzing the damage degree of rockfall phenomenon on roads and slopes in different scenarios,and proposing a combination of flexible protection and flexible shed hole as the disease treatment measures,based on which the comprehensive slope protection system and flexible shed hole structure design is carried out.Based on this,the comprehensive slope protection system and the structure design of flexible shed hole are carried out.The results of the study show that the road slope flexible shed hole integrated protection system designed based on actual working conditions and simulation analysis of falling rocks is conducive to slope stabilization.
