中文摘要:
      为保障景区游客及旅游设施的安全,本文运用人机遥感航空拍摄,生成实景三维立体模型,宏观分析危岩体的破坏模式。基于三维激光扫描技术,对仙宇屯东南面和西南面危岩带进行精准量测,获取危岩体几何尺寸、结构面产状、方量等崩塌参数,对危岩体的稳定性进行定性评价。结果表明,天然工况下,仙宇屯两处危岩处于稳定状态;暴雨工况下,处于不稳定状态。因危岩体与旅游栈道形成垂直威胁,分析计算采用长廊式的板棚治理措施以达到融入自然生态环境目的。
英文摘要:
      For the safety of tourist and travelling facility in the scenic spot,by UAV aerial photography and forms 3D dioramas,the breaking pattern of unstable rock is analyzed macroscopically. Based on laser scanner technology,the unstable rock in the southeast and southwest Xianyutun are tested accurately,geometry size,joint occurrence,volume and other parameters are acquired,then the stability of unstable rock is evaluated quantitatively. The result shows the unstable rock is stable in the natural condition but is unstable in the rain gush condition. Because the vertical threat of unstable rock and travelling trestle road along cliff,loggia palate tent treatment is used by calculation and analysis so the environment will be harmonious.
