求翻译：选取BP神经网络法作为验证模型，对块碎石路基适用性进行了验证评价，结果表明，经过训练学习，BP神经网络法也能够较为准确的对块碎石路基适用性进行评价预测。是什么意思？

Bp neural network method to validate the model and the applicability of the crushed rock embankment verify the evaluation results show that the trained learning bp neural network method can also be more accurate to evaluate the applicability of the block the gravel roadbed forecast.

Select BP neural networks as a model law, the applicability of roadbed pebble has been validated and the results showed that evaluation, a trained neural network learning, BP law is also to be able to more accurately to the gravel roadbed piece of application evaluation.

Selects the BP nerve network method to take the confirmation model, has carried on the confirmation appraisal to the block broken stone ballast serviceability, finally indicated, the process training study, the BP nerve network method also can more accurate carry on the appraisal forecast to the blo

Selected as a verification model using BP neural network method, block crushed evaluation of applicability has been validated, results showed that, after training, method of BP neural network to more accurate evaluation and prediction of fitness for a piece of crushed.
