摘　　要：双喇叭互通式立交是高速公路中一种较为特殊的立交形式,其改扩建涉及的影响因素多,改扩建设计的难度大。分析了双喇叭互通式立交改扩建设计的基本原则和主要影响因素,并以我国北方某条高速公路的互通式立交改扩建为例,探讨了双喇叭互通式立交改扩建方案的比选问题。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.
