| 摘 要： | 阐述了评价指标规范化处理在地质灾害危险性评价中的重要作用;针对传统线性规范化处理方法在实际应用中存在的不足,对评价指标危险等级的取值论域进行处理;基于模糊数学理论,提出直线型和曲线型2种规范化处理方法,使地质灾害危险性评价指标规范化处理更合理、更符合实际情况。实例应用结果表明,该规范化处理方法能较真实地反映地质灾害危险性等级。

| Abstract: | The important role of the standardized handling of risk evaluation indexes was described in the geological hazard.Considering the deficiencies of the traditional linear normalization method in the practical application,the domain of the risk level of evaluation indexes were conducted.Based on fuzzy theory,the linear and curve standardized handling method were established.It is more reasonable and more realistic for the standardized handling of risk evaluation indexes of geological hazard.The example shows that this method can be used to reflect truly the risk level of geological hazard. |
