公路隧道洞口3s设计速度行程与路线平、纵面线形关系探讨

Discussion on Designing Speed Stroke,Route Flat and Longitudinal Line in 3s Tunnel Portal

隧道工程在山区高速公路工程中占有较大的比重,隧道设计在高速公路设计中极其重要,通过对规范规定的隧道洞口位置3S设计速度行程与路线平、纵面线形一致的问题进行探讨,可为隧道设计洞口位置与平纵面线形组合设计提供参考。

Turmel engineering occupies a large proportion of highway engineering in mountainous area. Tunnel design is extremely important in the design of expressway. This paper discusses the problem of 3s design speed and tunnel alignment in line with the normative regulations, in order to provide a reference for the tunnel design of the location of the hole and linear combination design of fiat surface.
