岩溶塌陷稳定性的灰色模糊综合评判

根据建设用地地质灾害危险性评估的特点,选择4个一级因素和13个二级因素构建岩溶塌陷稳定性评估的两层次指标体系,通过模糊关系来刻画因素与稳定性等级间的关系、以灰度来描述信息的不充分程度,在此基础上介绍灰色模糊综合评判的建模方法。实例说明该方法的评价结果客观可靠,具有良好的实用价值。

Grey fuzzy synthetic assessment for stability of karst collapse

According to the characteristic of evaluating the dangers of geologic hazard of land used for building, this paper select 4 first-class factors and 13 second-class factors to build the two-levels indicator system of stability assessment of karst collapse, and describe the relation between factor and stability by fuzzy relation and the degree of information's insufficiency by grey scale, based on that to introduce method of building grey fuzzy synthetic assessment model. The application instance explains the evaluating result is impersonal and credible by the method, and has favorable application value.
