【摘要】 基于双曲线模型和灰色模型,采用误差绝对值加权和最小的准则,借助MATLAB软件计算加权平均数,创建了新的加权组合模型,并对某高速公路路基的沉降变形进行了预测分析.理论分析和实测结果表明,加权组合模型较前两种模型预测误差降低,得到了满意结果.新模型的提出为路基沉降变形预测提供了新的思路和方法.更多还原

【Abstract】 On the base of double-curve model and grey model,a new combined weighting model is built on the condition of the minimal absolute values of errors,in which the weighting average is calculated with MATLAB.By the settlement prediction analysis of a highway subgrade,the formula derivation and actual measurement results showed that the predictive error with combined weighting model was reduced,which is smaller than the ones with the two former methods,and the satisfactory results were obtained.So the new model provides a new idea and method for predicting subgrade settlement.更多还原
