Abstract
In order to study the changing characteristics of mechanical properties of pipelines after CIPP repair,the maximum principal stress and vertical displacement of pipelines after CIPP repair were analyzed by three-dimensional finite element model.The results show that the higher the corrosion degree,the greater the maximum principal stress and vertical displacement of the pipeline.After CIPP repair,the maxi-mum principal stress is significantly reduced,and the vertical displacement of the pipeline is reduced by about 23%,but it is slightly lower than the stress and displacement under normal state.In other words,the CIPP repair method has a certain repair effect on the corroded pipe-line,but it does not return to the initial state.Therefore,in actual pipeline maintenance,CIPP repair method can be used to repair pipelines with different degrees of corrosion to ensure safe operation of pipelines.关键词
