摘要
立交型式、方案的选择,应充分考虑交通量预测结果,地形、地物等实际情况,其型式的确定影响整个立交的功能、投资、安全、经济效益等方面。文中通过分析肇庆市国道321线大冲枢纽立交建设的主要控制因素,提出3种不同型式的立交方案进行比较,并选定最佳施工图设计方案,可以为类似立交的设计提供参考。
As the form of the interchange would have an impact on its function, investment, security and economic benefits, many factors, including predicted traffic, terrain, surface features and other aspects, should be taken into consideration while deciding the design proposal and form of an interchange. This paper analyzes the main control- ling factor of Dachong interchange on National Road 321 in Zhaoqing City Section, selects the best one out of three construction design solutions after comparison, which provides a reference for similar interchange design.
