摘　　要：针对含缺陷管道,运用有限元技术和数字可视化技术,基于Visual Basic环境开发管道腐蚀和裂纹缺陷分析程序。通过参数化数据输入,程序利用封装的ANSYS软件建立复杂形状的腐蚀模型,定义复杂裂纹,分析管道在内压、轴向力和弯矩下的应力响应,精细评估管道的剩余强度。通过工程算例验证了程序精度,表明程序能很好地描述工程实际,有较高的工程实用性。In order to complete strength analysis of pipelines containing defects based on the finite element technology and digital visualization technology,a pipeline assessment program for corro- sion defects and crack defects was developed using Visual Basic. Through inputting data paramet- rically,intensive assessment for residual strength of pipeline is made by integrating with ANSYS to build complex corrosion modal and define complex cracks,to get stress response of pipeline un- der internal pressure, axial force and bending moment. Finally, the accuracy of the program is veri- fied,which gives a good description of the engineering practice and has a high practicability.
