## Maximum Entropy Method for Determining Dam Safety Monitoring Indices

• 摘要: 运用最大熵原理从理论上推导了大坝监测数据的熵概率密度函数模型,在此基础上给出了大坝安全监控指标的计算方法。该方法直接根据样本的数字特征值进行推断,而不是先假设呈经典的概率分布,包含最少的主观假定,具有更充分的数学和物理意义,并且算法简单、便于应用。结合具体工程实例,并与传统方法进行对比分析,证实了该方法的有效性、可行性。

Abstract: The maximum entropy is used to generate the maximum entropy probability density function(MEPDF) of dam monitoring data,based on which the calculation method of dam safety monitoring index is provided.The MEPDF is concluded just from the digital eigenvalues of the dam monitoring data,not from the assumption of classical probability distribution,which includes the least subjective assumptions.Combined with engineering project,the efficacy and feasibility of MEPDF are proved based on the comparative analysis with the traditional method.
