摘要 西汉高速公路为国家高速公路网G5京昆高速西安-汉中段,是陕西省"米"字型公路主骨架的重要组成部分。涝峪河流域草沟因历史石灰石矿开采致使上部坡体发生崩塌,崩塌孤石在坡面多处分布形成高位危岩,直接威胁沟口西汉高速公路。论文以该高位危岩应急治理工程为实例,利用Rockfall软件对危岩失稳后运动轨迹、弹跳高度及冲击能量进行了模拟,并分析其变化规律,进而提出防治对策。 TheXihan Expressway from Xian to Hanzhong is one of the sections of G5 Beijing-Kunming Highway of National Highway Network which is also an important part of the highway main frame which is shaped like the Chinese character"Mi". The historical lime and quarry mining at Caogou on the north of Laoyuriver has caused the collapse of upper slope,and the collapsed boulder has distributed in the slope and gradually formed the high-level dangerous rock which directly threatens the Xihan Expressway. Therefore,with taking the contingency and governance project of high-level dangerous rock as the example,this thesis simulates the motion trail,bouncing height and impact energy of dangerous rock under instability by taking advantage of Rockfall,and then analyzes its changing rule,so as to proposes the control countermeasures.
