摘　　要：随着交通发展和经济的快速增长,山区交通建设成为当前重要的任务之一,如何在地形复杂的条件下,设计更加高效、安全的互通式立交成为山区高速建设重点考虑的问题。基于此,首先,阐述和分析山区互通式立交设计的主要制约因素,梳理了方案设计过程中需要遵守的主要原则。然后,结合工程案例,从控制因素的影响方面对立交设计方案进行深入分析和探讨。研究得出结论,在不同控制因素影响下的互通式立交方案设计具有一定的适应性和可塑性,通过对互通式立交的选型比较、匝道的迂回优化等措施,能够较好地适应山区的复杂地形及其他控制因素。该研究结果可为设计人员提供借鉴。With the development of transportation and rapid economic growth,the construction of transportation in mountainous areas has become one of the important tasks at present.How to design more efficient and safe interchanges under complex terrain conditions has become a key consideration for high-speed construction in mountainous areas.Based on this,firstly,the main constraints of mountainous interchange design are elaborated and analyzed,and the main principles that need to be followed in the scheme design process are summarized.Then,combined with engineering cases,conduct in-depth analysis and exploration of the overpass design scheme from the perspective of the influence of control factors.It can be concluded that the design of interchange schemes under different control factors has certain adaptability and plasticity.By comparing the selection of interchange schemes and optimizing the detour of ramps,it can better adapt to the complex terrain and other control factors in mountainous areas.Hope the research results can provide some reference for designers.
