公路软土路基沉降预测方法综述

Summarization about the Prediction Methods of Soft Soil Subgrade Settlement

传统路基沉降预测有指数曲线法、双曲线法、泊松曲线法等。近年来,由于灰色预测法、人工神经网络法等能反映全过程的沉降量与时间的关系,得到越来越多的应用。讨论了上述常用预测法的基本原理及优缺点,阐述了对某些方法的改进,介绍了某些有待推广的预测方法,具有一定的参考价值。

Traditional prediction methods of soft soil subgrade settlement include the exponential curve method, hyperbolic method,and Poisson curve method,etc.In recent years,the gray prediction method,and artificial neural network method,etc.are used more and more frequently because they could reflect the whole process of settlement-time relationship very well.This paper describes the basic principles of above-mentioned methods being in common use and their advantages and disadvantages,expounds the improvement of some methods,and introduces some prediction methods needing to be popularized with a certain value for reference.
