摘要
以汶马高速公路克枯大桥危岩为研究对象,通过野外调查,查明了危岩发育特征,结合赤平投影分析了其稳定性;利用离散元软件模拟,再现了区内典型危岩体WYT3-1的变形破坏全过程,并根据其变形破坏特征提出了针对性的治理措施建议。
This study finds out developmental characteristics of unstable rock mass at the Keku bridge of the Wenchuan-Markam Motorway and analyzes its stability with stereographic projection.The whole process of the deformation and failure of the typical dangerous rock WYT3-1 in the region is reproduced by use of the discrete element software,and some control measures are put forward according to its deformation and destruction characteristics.
