线形连续性是公路线形设计最基本的准则之一,线形连续性评价是高速公路线形适应性评价最主要的方面。文中在线形连续性以及现有评价方法分析的基础上,将灰色理论引入到连续性评价中来,并与单车车速差|85ΔV|指标相结合,建立了线形连续性灰色评价模型。同时,将模型运用于鹤岗高速相关路段,表明应用该方法是可靠的、准确的。 Linear continuity is one of the most basic criteria for highway alignment design. Linear continuity assessment is the most important aspect of highway linear adaptability evaluation. Based on the linear continuity and the analysis of existing evaluation methods, the gray theory is introduced into the continuity evaluation, and combined with the speed difference | 85ΔV | of the bicycle, a linear continuous gray evaluation model is established. At the same time, the model is applied to the related sections of Hegang Expressway, indicating that the application of this method is reliable and accurate.
