In order to calculate the corrosion rate of long-distance pipelines,CART was introduced to carry out the design and research of the following calculation method.A new calculation method is proposed by recommending the corrosion rate of typical pipeline soil environment,constructing a corrosion rate regression tree calculation model based on CART,pruning the regression tree,and calculating the long-term and short-term corrosion rates of long-distance pipelines.Through experimental analysis,it was found that the new calculation method can be used to calculate the constant pipeline corrosion rate,and the maximum corrosion rate of the pipeline section obtained through further calculation has extremely high accuracy,which can provide more reliable basis support for pipeline maintenance and repair.
