The prediction of remaining life and analysis of plane frame structure displacement reliability pipelines with corrosion defects are not only important parts of pipeline integrality and safety evaluation but also investigation keystone in the material field.Based on the GM(1,1) model of the gray theory and the JC method of the traditional structure reliability analysis method , the remaining life analysis software and the plane frame structure displacement reliability calculation analysis programme on corroded pipelines were developed by using softwares of VB and MATLAB.Aiming at the VB/MATLAB interface issue in the forecasting software,the ActiveX automation technology was used to connect VB with MATLAB,so that the powerful function of MATLAB in image processing and numerical computation and the advantages of VB in the interface design call be integrated.With simple desks ,easy operation and through some examples, the results are proved sound and the program's veracity.The analysis method could provide a basis for the prediction of remaining life,the reliability analysis of complex construction and the inspection cycle of pipelines,and have feasibility and practicality.
