摘要
城市互通立交的选型和设计越来越受到广泛重视,特别是针对既有平面交叉口随着交通量的增加须改造为互通立交的情况,涉及因素较多,设计难度较大。通过具体工程,对在既有平面交叉口改造互通立交型式的设计思路、设计原则、设计方法进行详细研究。
The selection and design of urban interchange are more and more important,and especially the existing grade intersection has to be reconstructed into the interchange with the increment of traffic volume.There are more involved factors and the design difficulty is larger.The article studies the design concept,design principle and design method of the existing grade intersections to be reconstructed into the interchange by the engineering cases in detail.
