根据云南省山区高速公路设计实例,结合区域地形、地质、气候等自然地理特点,总结云南山区高速公路存在的典型安全问题,并提出连续纵坡路段、长隧道路段、不良气候路段的设计对策,以期改进和优化设计方案,全面提高公路全寿命周期的安全性能,避免和减少运营后的安全改造工程,并为类似山区高速公路设计提供借鉴。
According to the design example of mountain highway in Yunnan Province, the typical safety problems of expressway in mountainous area of Yunnan Province are summarized according to the geographical features such as topography, geology and climate, and the design strategies for continuous longitudinal section, long tunnel section and bad weather section are proposed. With a view to improving and optimizing the design scheme, improving the safety performance of the highway in the whole life cycle, avoiding and reducing the post-operation safety renovation project and providing references for the design of similar mountainous expressways.
