摘　　要：在高速公路软土地基路段的建设过程中 ,考虑到软土地基的复杂性 ,为了控制施工进度 ,指导后期的施工组织与安排 ,如何利用沉降观测资料较为准确地推算后期沉降 (包括最终沉降 ) ,系统研究了曲线拟合法、灰色系统法、人工神经网络法、遗传算法等多种软土地基沉降预测方法的原理及其应用 ,为准确预测高速公路软土地基的沉降量提供了方法上的参考。During the building of expressway on soft ground,it is necessary to study how to accurately calculate the settlement of embankment to control the construction rate of progress and instruct the later construction plan. This paper introduces the theory and application of several forecasting methods of highway settlement on soft ground in common use,such as curve fitting method,GM (1,1) model, artifical neural network and genetic algorithm.It offers reference for accurately forecasting settlement of soft ground.8 refs.
