【摘要】 观音阁危岩位于四川省泸定县红军桥景区内的观音阁上、下陡崖位置,裂隙发育,局部呈碎裂状,危险性较高,直接影响景区内游客及工作人员的安全,同时威胁观音阁等景区建筑及附近居民房屋。通过对危岩的形成机理及基本特征分析,掌握危岩体的特点,对危岩的稳定性进行了定量分析及计算,结果表明,观音阁危岩在暴雨或地震等不利因素作用下极有可能崩落。根据危岩体的特点,观音阁下部危岩采取"格构+锚杆",上部危岩采取"支撑+锚杆"的综合治理方案,有效地解除了该危岩的安全隐患,为危岩的排危治理积累了经验。更多还原

【Abstract】 Guanyinge unstable rocks are located in Red Army Bridge Scenic Area of Luding County. Above and below the Guanyinge are unstable rocks,which are fracture,broken and dangerous. Guanyinge unstable rocks directly affect the safety of scenic spot and threat scenic construction and other residential buildings nearby. Through the analysis on the formation mechanism of Guanyinge rocks and basic characteristics,the characters are mastered and the stability is quantitatively analyzed and calculated. The results show that there is a high probability of rocks caving under rainstorm or earthquake and other unfavorable factors. According to the characteristics of the dangerous rock body,a comprehensive scheme of"lattice+ anchor"and "support + anchor"are taken for the lower part and the upper part respectively to remove the hidden danger and accumulate experience for hazardous treatment.更多还原
