基于改进神经网络的水泥路面使用性能预测模型
Portland Cement Concrete Pavement Performance Prediction Model Based on Improved Neural Network
【摘要】 为了克服传统水泥路面使用性能预测方法的缺陷和误差反向传播(BP)神经网络的不足,利用动量方法改进了BP神经网络收敛性,建立了水泥路面使用性能预测模型.采用广东水泥路面调查数据对模型进行了训练和验证,并对模型训练方法进行了优化.分析表明,该模型具有较好的实用性和预测精度.
【Abstract】 In order to deal with the deficiency of traditional prediction method of pavement performance and the insufficiency of Back-Propagation(BP) neural network,a prediction model based on the improved neural network with momentum Back-Propagation(MOBP) is developed.The model is validated and trained with pavement performance data of Guangdong province,and the training method is also optimized.According to the theoretical analysis and practical verification,the approach is completely feasible.
