摘要:

 如何实现大坝各单项评价由定性评价到量化评价的转化是大坝安全量化评价技术研究的关键点。通过研究大坝安全性态特点,首先确定大坝安全程度的特定量化评价值,然后结合数学分析工具Matlab,非线性拟合确定了基于Logistic生长曲线模型的大坝安全评价量化评价模型,精确拟合出量化评价参数,拟合决定系数达到0.998 6,实现了大坝安全单项指标评价由定性到量化的转变。

Abstract:

The key to assess dam safety is to qualitatively evaluate each individual indicator. We determine the specific quantitative evaluation values of the dam safety level, and then define the model parameters of the dam safety level by non-linear fitting mathematical analysis tool (Matlab). Thereby, on the basis of Logistic model, we can get a precise quantitative evaluation model, which accurately fits the quantitative evaluation parameters with the determination coefficient of 0.998 6. In this way, the qualitative evaluation of individual indicators is transformed into quantitative evaluation. 
