| 摘 要： | 公路超高设计计算中较有难度的是超高缓和段长度的确定、公式中参数的确定以及超高缓和段长度小于缓和曲线长度时超高缓和段的设置问题等。本文就这些问题从行车受力、路容美观、路面排水及施工可行性等方面进行了分析和讨论,阐明了设计计算的步骤和方法。

| Abstract: | There are some difficulties in highway superelevation design, especially in how to ascertain the length of superelevation runoff and the parameter in formula and how to superelevate a curve when the length of superelevation runoff is shorter than that of transition curve, and so on. This article mainly focuses on these questions from the forces on a running vehicle, esthetics of road, pavement drainage, and construction feasibility. It presents the process and method on design calculation, and some useful advice for superelevation design. |

| Keywords: | superelevation length of superelevation runoff types of superelevation transition curve superelevating gradual change of superelevation runoff |
