山地旅游景区落石灾害风险评估
Risk Assessment of Rockfall Disaster in Mountain Scenic Spots
摘要
Abstract
Based on the research background of Shepan Island scenic area in Sanmen County,Zhejiang Prov-ince,the influencing factors of rockfall disaster in mountain tourist attractions are comprehensively analyzed through field investigation and numerical analysis,and the risk assessment system of rockfall disaster in mountain tourist attractions is established based on RHRS risk scoring method.The results show that serious disturbance of surrounding rock,weathering of rock and chipping of public wall of adjacent cavern group are the three main influ-encing factors of rockfall.Based on RHRS risk scoring method,rockfall disaster risk is divided into 5 levels,and on this basis,a rockfall disaster risk assessment system is established in mountain tourist attractions.The engineer-ing practice shows that the analysis results of the established rockfall disaster risk assessment system are reliable,and the evaluation system can provide the basis for the occurrence of rockfall disaster early warning and treatment.关键词
