贵州境山区高速公路互通立交方案优化研究

摘要

According to the characteristics of large scale and multi-control factors of interchange project in mountainous area,combined withthe case of Liupanshui-Weining Expressway,the method for optimizing interworking schemes is explored.On the basis of planning and traffic volume a variety of interchange schemes are compared.Combined with the geological conditions,the project scale and other factors,the engineering investment is controlled and the best solution is determined.%针对山区高速公路互通立交工程规模大,控制因素多的特点,结合六盘水至威宁高速公路中的大河互通,探究互通方案优化的方法.根据规划及互通交通量,提出多种互通立交方案进行比较.结合互通区地质条件、工程规模等因素,控制工程投资,确定最优的互通方案.
