多种方法预测软基路堤沉降的应用对比分析

Application,Contrast and Analysis of Multiple Methods to Forecast Settlement of Soft Base Embankment

该文通过对对数曲线法、GM法、双曲线法、分层总和法在预测路堤沉降的对比分析,对每种方法的适用条件提出了评价,同时也验证了这四种方法的适用性,提出了怎样更好进行路堤沉降预测的建议,选取了预测模型及方法预测未来路堤沉降量,对防治公路路堤沉降,保证公路良好的营运质量具有重要的理论价值、经济价值及工程实际意义。

Through the contrast and analysis of logarithmic curve method,GM method,double-curve method and layerwise summation method in the forecast of embankment settlement,the article puts forward the evaluation for the application condition of each method,at the same time,also verifies the applicability of these four methods,puts forward the suggestion how to forecast the embankment settlement better and selects the forecast model and method to forecast the embankment settlement in the future,which have the importantly theoretical value,economical value and engineering practical significance to prevent the embankment settlement of highway and to guarantee the good operation quality of highway.
