线路软土地基沉降预测方法分析对比

Analysis and comparison of route soft soil base sinking prospecting mathods

对软土地基沉降常用的计算方法进行了综述,并用规范中的两种曲线拟合方法及BP人工神经网络法进行分析与预测,从各种拟合预测曲线及实测曲线的比较中可以看出,BP人工神经网络法能够更加准确地对软土地基沉降进行预测,且人为因素较少,比较符合客观实际,为软土沉降预测方法的选用提供参考。

It narrates common calculating methods of soft base sinking, makes analysis ans comparison on two curves combining method and BP artificial nerve net method. From the comparison between each combining prospect curves and actual curves, we can see that BP artificial nerve net method can do more accurate observation on soft base sinking, and have less contrived factors which is more suitable to the fact, and offers reference for soft base sinking observation methods.
