摘要:
为提升含腐蚀缺陷管道失效压力预测精度，准确把控管道状态，建立基于DE-BPNN的含腐蚀缺陷管道失效压力预测模型，有效避免BPNN模型陷入局部最优问题，提升预测精度。基于61组管道爆破实验数据，分别用DE-BPNN与BPNN模型进行仿真计算。结果表明：DE-BPNN预测结果平均相对误差为3.26%，R2为0.985 85，预测精度较BPNN模型有明显提升。应用DE-BPNN模型预测含腐蚀缺陷的管道失效压力可为长输管道运输调配和检维修提供决策支持。
Abstract:
To improve the prediction accuracy of the failure pressure of pipeline containing corrosion defects,and accurately control the pipeline state,a failure pressure prediction model for the pipeline with corrosion defects based on DE-BPNN was established.DE performed an optimized search on the initial weights and thresholds of the BPNN,which effectively avoided the problem of BPNN model falling into the local optimum,thus improved its prediction accuracy.Taking 61 sets of pipeline blasting test data as example,the DE-BPNN and BPNN models were used to perform the simulation calculation in Matlab respectively.The results showed that the average relative error of DE-BPNN prediction results was only 3.26%,with R2 of 0.985 85,and the prediction accuracy was significantly improved comparing with the BPNN model.The application of DE-BPNN model to predict the failure pressure of pipelines containing corrosion defects can provide decision support for the transportation deployment,inspection and maintenance of long-distance pipelines.
