摘　　要：以浙江省三门县蛇蟠岛景区为研究背景,通过现场勘察与数值分析等手段,全面分析了山地旅游景区落石灾害的影响因素,基于RHRS风险评分方法建立了山地旅游景区落石灾害风险评估体系。研究结果表明:古洞室群围岩的严重扰动、岩石的风化作用、相邻洞室公共墙体的凿去为落石的三个主要影响因素;基于RHRS风险评分方法将落石灾害风险划分为5个等级,并在此基础上建立了山地旅游景区落石灾害风险评估体系;工程实践表明,建立的山地旅游景区落石灾害风险评估体系分析结果可靠,该评价体系可为落石灾害的发生提供预警及治理提供依据。Based on the research background of Shepan Island scenic area in Sanmen County,Zhejiang Province,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 influencing 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 engineering 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.
