| 摘 要： | 针对传统大坝安全监控指标的拟定方法具有一定局限性的问题，在分析原始监测数据的基础上，通过正、逆向云发生器产生监测数据的期望、熵、超熵等数字特征，利用这些数字特征计算定量的转换值，从而实现定量—定性—定量的转换，进而确定安全监控指标，以某混凝土重力坝为例，运用云模型拟定了该坝#9坝段坝顶水平位移安全监控指标，并与典型小概率法的拟定结果进行了对比分析，验证了云模型的优越性。

| Abstract: | Considering the limitations of the traditional methods in determining dam safety monitoring index, on the basis of analyzing original monitoring datas, this article makes use of the backward and forward cloud model calculating the digital characteristic values of original monitoring datas and realizing the quantitative to qualitative to quantitative conversion to determine the safety monitoring index. Taking a certain concrete gravity dam for an example, the safety monitoring index of the dam crest horizontal displacement of the dam section #9 is determined and it makes comparisons with the typical small probability method. The results proves the superiority of the cloud model in determing the safety monitoring index. |
