摘要
互通式立交作为高速公路的重要组成部分,方案设计的优劣,对工程的投资、效益及技术等级、服务水平的高低以及行车安全都将产生直接的影响,立交方案的选择对高速公路的修建至关重要。以罗望高速公路坝算枢纽互通为依托,提出考虑不同侧重点的多个互通设计方案,从工程规模、技术指标、车流组织及实地限制条件等多方面进行综合比选分析,合理选择互通方案,为类似工程设计提供借鉴和参考。
As an important constituent part of expressway,the advantages and disadvantages of scheme design on interchange will directly influence the investment,benefit and technical grade of the project,service level and traffic safety. Therefore,the selection for interchange scheme is crucial to the construction of expressway. Basing on Basuan hub interchange of Luodian- Wangmo Expressway,design schemes for some interchanges considering different emphasis points are put forward,comparison and selection analyses on some aspects like project scale,technical index,organization of car flow and on- site limiting condition and so on are performed,and the scheme for interchange is selected reasonably,thus providing reference for similar project design.
