摘　　要：山区高速公路受地形、地质条件和走廊带狭窄等因素制约,采用常规单喇叭互通设计往往工程规模大、工程造价高,因此对山区高速公路互通选型设计进行了比选研究。研究结果表明:山区高速公路互通方案设计应充分利用有利地形,结合交通量预测结果,合理选择技术指标,以降低工程规模。The design of interchanges on mountainous expressways is constrained by factors such as terrain,geological conditions,and the narrowness of corridor areas.Consequently,the conventional single trumpet interchange design often results in large project scales and high costs.Therefore,a comparative study on the selection and design of interchanges for mountainous expressways has been conducted.The research findings indicate that the design of interchange schemes for mountainous expressways should fully utilise advantageous terrain,incorporate traffic volume forecasts,and reasonably select technical indicators to reduce project scale.
