Hidden Danger Analysis And Prevention Methods Of Tourism Geological Disaster In Mountain Area

Mountainous tourism resources are abundant in China.With the rapid development of mountain tourism resources,geological disasters occur frequently in mountain tourism areas,including landslides,collapses and debris flows,may occur.Among them,the collapse disaster has the characteristics of concealment,sudden occurrence,calamity and so on.However,there are not many methods to prevent and solve geological disasters in mountainous tourist areas.In this paper,the exit section and yingyangmen section of Yeren Cave Scenic Area of Snake Island National Mine Park in Zhejiang Province are selected as the research area,and the corresponding geological model is established.The stability of dangerous rock is evaluated by using the technology of field investigation and numerical simulation.The influence range of rock fall is calculated by using RocFall software,and the corresponding prevention measures are provided for the prevention and control of scenic area.The main research work and results are as follows:?1?A detailed engineering geological survey was carried out in the study area to find out the geological characteristics of the dangerous rock mass on the side slope of the cavern and to make a preliminary stability evaluation.?2?According to the dangerous rock mass of the exit slope,the risk of geological disaster under the condition of tourism is evaluated,and the conclusion that the slope is a high-risk area is obtained.RocFall software is used to simulate it,and the movement characteristics and influence range of the rock fall are obtained.Based on the principle of engineering geological method of mountain tourism planning,the"slope cutting,mortar layer,concrete slab,anchor"is proposed Strengthening and prevention methods of"consolidation and greening".?3?According to the dangerous rock mass in yingyangmen section,the point cloud data is obtained by using 3D laser scanning technology,and the stability of dangerous rock mass in the study area is simulated and calculated by using GeoMagic,HyperMesh and FLAC^3D software.The information such as stress field,displacement field and plastic area of dangerous rock mass is obtained,and the conclusion that the stability of dangerous rock mass is poor and rock collapse may occur is obtained.Based on the mountain tourism planning project Based on the principle of geological method,a comprehensive and parallel prevention method of"engineering reinforcement"and"bypass"is proposed.
