摘要: 依托桂林阳朔如意峰旅游景点项目开发,针对项目建设中A4救生平台基础存在的安全隐患问题,通过现场调查和理论分析相结合的方法,采用赤平投影定性分析和极限平衡法、有限元数值模拟法定量计算相结合的方式,对如意峰景区A4救生平台基础岩体稳定性进行综合评价,分析表明A4救生平台基础岩体处于不稳定状态,需对其进行加固处理,并提出了加固处理建议措施,为后期危岩崩塌的治理提供理论支撑和科学依据,对岩溶地区类似岩体的稳定性研究具有一定的参考价值。Abstract: This work makes an assessment of the stability of the rock mass beneath the A4 rescue platform during the construction of the Ruyifeng scenic spot project in Yangshuo, Guilin. It builds on the combination of the methods of field surveys and theoretical analysis including stereographic projection qualitative analysis, the limit equilibrium method and finite element numerical simulation. The results show that the rock mass beneath the A4 rescue foundation is in an unstable state thus needs to be reinforced. Additionally, we puts forward the reinforcement treatment measures so as to provide theoretical support and scientific basis for the treatment of later possible collapse of the dangerous rock, which would be a certain reference for the stability research of similar rock masses in karst areas.
