摘要
根据丰沙(丰台—沙城)线下行K54+080—K54+124右侧边坡危岩体发育分布情况,应用基于静力解析法的崩塌落石灾害风险评估方法做出评价。评价得到的风险等级可表征为风险事故发生的概率和事故损失的乘积。风险事故发生的概率是基于静力解析法,应用Rock Science软件分析和预测落石的运动特征来表征事故的损失,并且提出了更新和修补挡墙的防治措施,降低落石冲击风险。
The rock mass around the right slope of the down line of Fengtai-Shacheng Railway K54＋080—K54＋124 was analyzed.With the static analytical method,the rockfall disaster risk assessment was conducted.The assessed risk level may be expressed as the product of the accident probability and the accident loss.The accident probability is calculated with the static analytical method.The accident loss is indicated by the kinematics of the rockfall through the analysis and prediction with RockScience software.The renovation and repair of the retaining wall were presented,which reduced the impact risk of the rockfall.
