[0052] Such as figure 1 As shown, a method for predicting the risk of pipe burst in a water supply network based on Bayesian survival analysis, the method includes the following steps:
[0053] (1) Establish a pipe burst database according to the collected pipe burst history data, and extract key information as covariates;
[0054] (2) Carry out spatial clustering analysis on the squib points, and quantify the spatial distribution information of the squib points as a new covariate to supplement the squib database;
[0055] (3) Based on the pipe burst database, a Bayesian survival analysis method is used to construct a pipe burst risk prediction model;
[0056] (4) Using the pipe burst risk prediction model to predict the pipe burst risk.
[0057] Step (1) Aiming at the pipe burst incident, record the relevant pipe burst information in detail, which is the data basis for analyzing the cause and law of the pipe burst, and even formulating prevention and emergency strategies. T...
