摘　　要：对大坝安全监测资料进行分析是掌握大坝安全运行状态的主要方法。在进行资料分析过程中一般认为监测资料是精确可靠的,而事实上,由于服役环境的复杂性,大坝安全监测系统会随时间表现出不稳定性,从而影响到监测资料的可信度。以监测系统的可靠性为研究对象,提出基于模糊数学和重心法的大坝安全监测系统综合评价模型,并用于某工程实践,计算结果表明该模型具有一定的实用价值。Analysis of the dam safety monitoring data is the main approach to find out the working state of a dam .Usual-ly , the monitoring data is considered to be accurate and reliable .However , temporal instability is inevitably appeared in the dam safety monitoring system due to the complexity of its working environment , which could affect the reliability of the monitoring data .Thus, a comprehensive evaluation model of the dam safety monitoring system based on fuzzy mathe -matics and the gravity center method is proposed to study the reliability of the monitoring system .Engineering application results show that the proposed model is of certain practical values .
