对《公路工程技术标准》(JTG B01-2003)中关于隧道洞口平面“线形应一致”的理解分歧,将会对隧道平面线形设计、工程规模、自然环境以及行车条件等产生重大影响。分析、探讨隧道洞口平面线形规定为“线形应一致”的含义,尝试通过安全性分析,基于运行速度与交通安全关系的角度,提出了公路隧道洞口平面线形设计的几点建议。
The disagreement on the “linear consistency” of tunnel openings in the “Technical Standards for Highway Engineering” (JTG B01-2003) will have a significant impact on the flat-shaped design of the tunnel, the scale of the project, the natural environment and driving conditions. The paper analyzes and discusses the meaning of “the line shape should be consistent” in the regulation of the plane line shape of the tunnel entrance, and tries to put forward some suggestions on the plane line shape design of the highway tunnel entrance based on the safety analysis and the relationship between the running speed and traffic safety.
