摘要
地质灾害危险性评估工作级别由建设项目重要性和评估区地质环境条件复杂程度这两个因素决定。在分析现行相关标准和研究成果的基础上,指出建设项目重要性可依次由省部级相关技术标准、项目行政审批权限级别、预估灾后损失程度顺序确定,以先符合者为准;指出评估区地质环境条件复杂程度可由地质灾害发育程度、地形与地貌复杂程度、地质构造复杂程度、岩土体工程地质性质、水文地质条件、破坏地质环境的人类工程活动程度等6项判定因素确定,并初步确定了地质灾害发育程度、地形与地貌复杂程度、地质构造复杂程度、岩土体工程地质性质、水文地质条件和破坏地质环境的人类工程活动程度等分级评价标准。
Grading of geological hazards risk assessment could according to two factors as the importance of the construction projects and the complex degree of geological environmental conditions in the assessment area. On the basis of analyzing the current relative standards and research results, it is pointed out that the importance of a construction project could be determined by relevant technical standards of the ministerial and provincial levels, the grade of administrative examination and approval power of project and estimation of disaster loss degree in turn. And it is also pointed out that the complex degree of environmental geological condition in an assessment area could be decided by six factors, that are the development degree of geological hazards, the complex degree of topography and geomorphology, the complex degree of geological structure, engineering geological characteristics of rock and soil, hydrogeology conditions, and human engineering activities which damage geological environment. Preliminary grading standards for the six factors are determined.
