摘　　要："十三五"交通规划即将收官,前一阶段建设的公路服务水平正在逐年下降,公路改扩建工程占比则逐年提高。拟合设计是改扩建工程中特有的设计环节,其优劣直接影响到工程质量与工程造价。通过统计学中参数估计与假设检验的手段,从理论上探讨了对于拟合成果的评价标准,同时应用此方法,对浙江省某高速公路改扩建项目的拟合成果进行评价,对于工程设计人员具有一定的实践意义。With the closing of the master planning of transport for the 13 th Five-Year Plan,the level of road service constructed in the previous years is declining year by year,and the proportion of road reconstruction and expansion projects is increasing.Fitting design is a unique design link in the reconstruction and expansion project,and its advantages and disadvantages directly affect the project quality and engineering cost.In this paper,through the means of parameter estimation and hypothesis testing in statistics,the evaluation criteria for fitting results are theoretically discussed.At the same time,the method is used to evaluate the fitting result of an expressway reconstruction and extension project in Zhejiang Province,which has certain practical significance for designers.
