摘要
以西安市地铁一号线建设工程地质灾害危险性评估为例,对综合评估量化评分方法进行了理论探讨和实例分析,主要讨论了评估因子的选取、各因子权重和分级取值、危险性等级划分和各级分值范围确定、评分方法和步骤等几个方面的内容。实例分析结果表明,基于本文量化评分方法基础上的地质灾害危险性分区能够较好地反映多因素的综合影响,评估结果合理可信。
Taking the geological disaster assessment of No.1 subway in Xi an as an example,Theoretical discuss and practical analysis are made on quantification grading method.The selection of assessment factors,weight of each factor and its value,division of risk grade and its scope and score,scoring methods and steps are discussed.The practical analysis result shows that this method can better reflect the comprehensive influence of multi-factor,and the result is reasonable and creditable.
