Dam operation life evaluation method based on dam actual measurement monitoring data

The invention relates to a dam operation life evaluation method based on dam actual measurement monitoring data. The method is suitable for dam safety evaluation. According to the technical scheme, the method comprises the steps that S1, a dam operation risk evaluation system is established, wherein the dam operation risk evaluation system comprises multiple dam operation risk factors; s2, determining key risk factors influencing the operation safety of the dam; s3, determining representative measuring points of the key risk factors, wherein the number of the measuring points is greater than or equal to 1; s4, analyzing the risk degree of a single measuring point; s5, calculating the comprehensive risk degree of dam operation; s6, constructing a dam time-varying risk degree model based on a Markov chain; s7, calculating a state transition matrix; s8, according to the state transition matrix, calculating the comprehensive risk degree of dam operation for many years in the future; s9, establishing a dam operati
