隧道进出口线形过渡一致性评价探讨

结合国内外运行车速调研及辽宁省部分高速公路运行车速实测及有关调查,建立高速公路隧道进出口运行车速预测模型及线形设计一致性标准,确定隧道进出口线形一致性评价指标,提出高速公路隧道进出口线形一致性设计建议值。

Discussion on Consistency Evaluation of Linear Transition at Tunnel Entrance and Exit

Combining the domestic and foreign studies on vehicle speed with measured vehicle speed in several expressways in Liaoning Province and related investigations,prediction model of vehicle speed at expressway tunnel entrance and exit and the consistency standard of linear design are established,and evaluation index of linear consistency at tunnel entrance and exit is determined,and recommended value of linear consistency design at expressway tunnel entrance and exit is proposed.
