Buried pipeline service performance evaluation method, computer readable medium and equipment

Abstract

The invention relates to a buried pipeline service performance evaluation method, a computer readable medium and equipment. A buried pipeline service performance evaluation method comprises the stepsthat S1, a buried pipeline model is constructed in combination with influence variables, and a regression equation of pipeline stress and the influence variables is obtained; s2, constructing a relation curve between influence variables and pipeline stress based on the regression equation; s3, variable measurement data in the actual working condition of the pipeline are measured, and the service life of the pipeline is predicted. According to the method, the built pipeline service performance evaluation model is adopted, the stress of various buried pipelines under multiple diseases and complex service conditions can be directly solved, the contribution percentage of variables contained in an equation to the pipeline stress is calculated, and the residual life of the pipelines is predicted.

Description

technical field [0001] The invention relates to the field of pipeline performance evaluation, in particular to a buried pipeline service performance evaluation method, computer-readable medium and equipment. Background technique [0002] Due to the long service life of the buried pipelines built in the early stage, various diseases such as void at the bottom of the pipeline, corrosion of the inner wall, cracking of the pipe body, and leakage coexisted under the coupling effect of various internal and external factors, resulting in pipe bursts, road collapse, etc. The possibility of accidents increases dramatically. Therefore, how to assess the service status, remaining life and repair priority of these old pipelines has become a serious problem for municipal organizations. [0003] At present, analytical method and semi-empirical method are mainly used to solve pipeline stress. Although these methods are widely used in practice, their scope of application is severely limit...

AI Technical Summary

Problems solved by technology

This evaluation method has the following problems: (1) the use of a single average length index cannot reflect the real situation of pipeline defects; (2) the evaluation is only based on the apparent inspection results, without distinguishing the relationship between defects and pipeline materials; (3) The evaluation process lacks scientific quantification and theoretical basis; (4) The remaining life of the pipeline cannot be predicted

[0005] Therefore, there are deficiencies in the existing field of performance evaluation of buried pipelines, which need to be improved and improved.
