摘要
随着社会经济的发展和山区大型基础设施的兴建,山区公路的建设步伐正在不断加快。山区公路具有山高坡陡、地势险要、地形与地质条件复杂、制约因素众多等特点,从而导致山区公路设计工作十分复杂。结合山区公路的特点和工程实例,分别从公路等级的选择,平、纵、横技术指标的运用及避险车道的设置等方面,阐述了山区公路设计时应注意的事项及采取的对应措施。对山区公路建设具有针对性的指导意义。
With the development of society and economy and the construction of large scale infrastructures in the mountain area, the construction of highway is speeding up. The geological conditions in mountain area are complicated with high mountains, steep slope and other restrictions and influential factors. Therefore, the design of the highway in mountain area is complex. Combining with the characteristics and practical projects, the precautions and countermeasures in the design are put forward, from the perspective of the selection of highway grade, application of indexes of horizontal, vertical and transverse technological indexes and the setting of emergency lane.
