摘　　要：为使现行《地质灾害危险性评估规范》更加适用于山区地质灾害危险性评估工作,分析探讨了规范中涉及的地质灾害危险性分级因素、危害程度分级、预测评估方法、危险性分区范围、防治措施建议等相关问题,进而指出应根据现状地质灾害的稳定程度、危害程度判断其危险性,根据险情判断其危害程度,并提出了危险性分级参数的修改建议值,提出了基于预先危险性分析(PHA)的预测评估方法,明确了危险性分区范围与治理责任的相关性,指出应综合考虑受灾体的重要性及地质灾害发生的可能性等因素,分类提出保护、搬迁、治理、监测等防治措施建议。In order to make the current“Specifications for risk assessment of geological hazard” more applicable to mountain geological hazard risk assessment, analyzes and discusses the factors of geological hazard classification, hazard degree classification, prediction and evaluation method, risk zoning scope, prevention and control measures and other related problems involved in the specifications, further, it is pointed out that the hazard should be judged according to the stability and hazard degree of the present geological hazards, and the hazard degree should be judged according to the dangerous situation, and suggested values of risk classification parameters are proposed, the prediction and evaluation method based on pre-hazard analysis(PHA) is put forward, and the relativity between the scope of hazard zoning and the responsibility of management is defined, it is pointed out that the importance of disaster-stricken body and the possibility of geological disaster should be considered comprehensively, and some suggestions on prevention and control measures such as protection, relocation, management and monitoring should be put forward.
