浅埋明挖隧道合理结构断面型式比选

Comparison and Selection of Rational Structural Section Types of Shallow Open-excavated Tunnel

文章针对常见的双向六车道公路隧道,拟定不同的断面型式,从功能要求、结构受力、材料用量、经济性及适用性多角度进行比选,并针对一些特殊性的超宽超深断面提出解决方案和建议,对管廊设置与否进行了详尽的阐述,为类似隧道工程的设计提供依据。

According to the common two-way six-lane highway tunnel,this paper draws up different section types and compares them from the aspects of functional requirements,structural forces,material consumption,economy and applicability。The solutions and suggestions are put forward for some special ultra-wide and ultra-deep sections and the installation of the pipe gallery is expounded in detail,which provides a basis for similar tunnel engineering design.
