基于灰色聚类法和灰色关联分析的大坝安全评价

摘要

大坝安全评价是一项复杂的综合评价，针对大坝安全评价中存在信息不完全确定的特点，将灰色系统理论中的灰色聚类法和灰色关联分析法应用到大坝安全评价中。以大坝基础工程部位的安全状况作为评价对象，建立评价指标和评价标准体系。通过实例计算与分析表明，两种方法在安全评价结果方面表现出了良好的一致性，且评价结果与实际情况相符，将两种方法用于大坝安全评价是可行和有效的。%Dam safety evaluation is a complex and comprehensive evaluation ,according to the characteristics of incomplete information in dam safety evaluation .The grey clustering method and grey relational analysis method are applied to the dam safety evaluation .With the security situation of dam foundation engineering parts as evaluation object ,a system of evaluation index and standard is established .Through the practical calculation and analysis ,it indicates that results of two methods in the safety evaluation show a good consistency ,and the evaluation results are consistent with the actual situation ,of which the two kinds for dam safety evaluation and feasible and effective .
