| Abstract: | Double trumpet interchange is one particular type in the expressways of China.There are many influencing factors in reconstruction and Extension of this kind interchange.So the design of reconstruction and Extension of double trumpet interchange is difficult.In this paper,the influencing factors of reconstruction and Extension schemes of double trumpet interchange are analyzed.The fundamental design principles of the double trumpet interchange reconstruction project are concluded.Taken the example of the reconstruction design schemes of one double trumped interchange in North China,scheme alternative problem of reconstruction and Extension schemes of double trumpet interchange is discussed. |
