山区高速公路总体设计研究

Overall Design of Mountainous Expressway

山区高速公路因独特的地形、地质、水文、生态等问题,使得工程技术复杂、规模巨大、造价极高。总体设计是山区高速公路工程项目的挈领和总纲,要求协调项目与外部环境之间、项目内部各专业之间的关系,综合各种影响因素确定适当的标准、规模、方案,以形成协调、完整的系统工程,实现山区高速公路安全、环保、可持续发展的总体目标。文章通过对山区高速公路特点的分析,归纳了山区高速公路总体设计的主要控制因素,并结合新时代"绿色、智慧、一体化"的新要求,提出了山区高速公路总体设计理念和主要设计原则,较为系统地论述了各专业在总体设计中的设计要点及关键应对措施,可为同类工程提供借鉴。

The mountainous expressway has complicated engineering technology,huge scale and extremely high cost due to unique topography,geology,hydrology,ecology and other problems.The overall design is the guideline and general outline of the mountainous expressway project.It requires to coordinate the relationship between the project and the external environment,and between the various disciplines within the project,and to determine the appropriate standard,scale and scheme by integrating various influencing factors,so as to form a coordinated and complete system engineering and realize the overall goal of safety,environmental protection and sustainable development of mountain expressway.Based on the analysis of the characteristics of mountainous expressways,this paper sums up the main control factors of the overall design of mountain expressways.Combined with the new requirements of"green,wisdom and integration"in the new era,the paper puts forward the overall design concept and main design principles of mountainous expressway,and systematically discusses the design points and key countermeasures of various specialties in the overall design.The research results can provide reference for similar projects.
