摘要
基于拟建杭(州)绍(兴)台(州)高速公路沿线大岙溪危岩,从地质环境条件入手,通过现场勘察,归纳危岩发育特征,分析其形成机制;利用RocFall软件数值模拟,系统分析危岩可能发生崩塌落石后的运动轨迹,计算落石在拟设高速公路部位的冲击能量等运动学参数,评价对拟建高速公路桥墩的危害性,并提出了针对性的治理措施建议。
Based on the DaAoXi unstable rock along proposed HANG-SHAO-TAI highway,starting from the geological environment condition,the develomental characteristics of dangerous rock are induced,and the formational mechanism is analysed by field survey.Using RocFall simulation,the trajectory of the rockfall when they collapse along slope is researched,and the kinematic parameters of rockfall,such as kinetic energy,in the proposed highway position are estimated.The destructiveness of rockfall to the proposed highways＇ bridge pier are evaluated,and the targeted prevention measures are proposed.
