摘 要:越江越海隧道作为一种常见的下穿式公路隧道,已广泛应用于我国许多城市,但由于其通常存在较长的纵坡并且承担着较大的运输压力,导致交通事故频发。为降低越海越江隧道的交通事故风险,本文提出彩色路面和减速标线相结合的越海越江隧道入口综合改造设计方案,并通过问卷调查方式采集驾驶员对各个方案的主观感受,运用聚类分析区分不同事故风险人群,探究不同风险驾驶员对方案的选择情况,据此筛选出合理的初期设计方案。并以长江隧道为具体案例,计算彩色路面长度,鱼刺标线宽度、角度、间距等关键参数,提出了细化的彩色路面综合设计改造措施。As a common underpass highway tunnel, river crossing and sea crossing tunnel has been widely used in many cities in China. However, due to its long longitudinal slope and large transportation pressure, traffic accidents occur frequently. In order to reduce the traffic accident risk of the cross sea and river crossing tunnel, this paper puts forward the comprehensive reconstruction design scheme of the cross sea and river crossing tunnel entrance which combines color pavement and deceleration marking. By means of questionnaire survey, the driver’s subjective feelings on each scheme are collected, and different accident risk groups are distinguished by cluster analysis, and the selection of schemes by different risk drivers is explored. The reasonable initial design scheme is selected. Finally, taking the Yangtze River Tunnel as an example, the key parameters such as the length of color pavement, the width, angle and spacing of fishbone markings are calculated, and the detailed comprehensive design and reconstruction measures of color pavement are proposed.
