中文摘要：

崩塌落石是西南山区常见的地质灾害,为合理地治理崩塌落石灾害,基于对某采气场进场道路崩塌边坡的详细野外调查,评价了该边坡的稳定性,同时采用运动学原理计算了崩塌落石的运动特征量,并利用Rockfall软件进行数值模拟验证,模拟结果与运动学原理计算结果相符合,最后针对该边坡所带来的安全隐患,提出了＂清除危岩＋拦石墙＋落石槽＂的防护措施。

英文摘要：

Collapses and rockfalls are common geological disasters in southwest mountainous areas .In order to effectively control and manage the disasters ,a detailed survey on a collapsed slope of the access road to a gas field was carried out , followed by the evaluation of the slope stability .Meanwhile ,the motion characteristic quantity of the rock fall was calcu-lated using kinematics and then verified with the simulation software Rockfall .The simulation results showed consistency with the kinematics .Finally ,regarding to the collapse hazards of this slope ,the control measure of “clear dangerous rocks ,install stonewall bars and rock fall collection channels”was proposed .
