Abstract: The preparation of dam safety monitoring indicators can effectively monitor the long-term operation and maintenance of reservoir dams.At present, there are few comparative studies on the monitoring indicators prepared by the maximum entropy method and the traditional classical probability density function method.In this paper, the sluice pier of the Wangfuzhou hydro-junction was taken as an example, and the monitoring data series under adverse load conditions were selected to form small samples.The K-S test method and the maximum entropy method were used to determine the extreme probability density function, and then the small probability event method was used to draft the monitoring indicators.The research results showed that the probability density function of the extreme horizontal displacement of the typical sluice pier determined by the K-S test method basically met the normal distribution, and its probability density function curve was close to the probability density function curve determined by the maximum entropy method.The displacement monitoring indicators prepared by the two probability density functions using the small probability event method were also close.
