  要:公路路线设计规范》中已根据一般车辆的种类及外轮廓尺寸提出了曲线路段路面加宽值。在实际运用中,因道路使用功能的需要,车辆外轮廓尺寸超出一般车辆最大尺寸范围,现行规范中的加宽值无法满足其使用需求。本文结合大河坝至黄金峡交通道路工程设计实例,利用国内、外曲线加宽计算模型,详细介绍了超长、超宽车辆平曲线加宽值的验算及实际运用方式,以期为同类设计提供参考。

AbstractIn Design Specification for Highway Alignmentthe road widening value of the curve section is put forward according to the types and contour profile sizes of ordinary vehicles. Whereas in practical applicationthe contour profiles of some vehicles exceed the maximum sizeand the widening value in the current specification cannot meet the demands of those vehicles under the need of road using.Combining the example of engineering design for the road from the DA HE BA to HUANG JIN XIAthe checking calculation and application of widening values of horizontal curve for super long and extra wide vehicles was introduced in detail by the the model of curve widening at domestic and internationalwhich could provide reference for designs of the same kind.
