山区的岩体受构造裂隙切割,岩体破碎,易发生崩塌。老五大寺危岩主要的破坏模式为倾倒式和滑移式两种,通过定性和定量分析可知天然条件下,危岩体处于稳定状态,暴雨或地震条件下,危岩体处于基本稳定-欠稳定状态。针对保护对象,治理方案以“被动拦石网”为主,局部设置拦石墙。 The rock mass in mountainous area is cut by the structural fissure, the rock mass is broken, and collapse easily occurs. The main failure modes of the old Wudaisi rock are dumping and sliding. Through qualitative and quantitative analysis, the dangerous rock mass is in a steady state under natural conditions. Under heavy rain or earthquake, the dangerous rock mass is basically stable - stable state. For the protection of objects, governance programs to “Passive Stone ” mainly set up to block the wall.
