A New Method of Dam Crack Safe-Monitoring Based on the Markov Chain

Abstract:

How to identify and remove the noise of the dam monitoring data is an important work of dam safety-monitoring. The article makes use of a new compromise thres-holding method to de-noise the dam horizontal dam crack width. Afterwards, the article uses the Markov correction model to predict the crack width of the dam body based on the de-nosing data. In order to identify the effectiveness of the model, the article makes a comparison between the results of the above method with that of the multiple regression method. And the results show that the method of the article is of effective.
