摘要
大坝安全监测系统复杂,各个指标之间存在着不确定性。D-S证据理论作为一种数学工具,在不确定性的表达、组合等方面的优势受到重视。提出一种信息融合D-S证据理论方法应用于大坝安全监控中,以提高大坝安全评价的准确性。并以青铜峡水利枢纽的监测数据为例进行了实例分析,结果表明D-S证据理论是一种科学的安全评价方法,是可行的,有效的。
Dam safety monitoring system is complex as uncertainty exists among various indicators. D-S evidence theory as a mathematical tool has been taken seriously for its advantages in expression and combination of uncertainty. A data fusion method of D-S evidence theory is applied to dam safety monitoring in order to improve the accuracy of dam safety evaluation. A case study is made on monitoring data of Qingtongxia Hydro-complex, and results show that the D-S evidence theory as a scientific safety evaluation method is feasible and effective.
