| 摘 要： | 在山地城市建设和江河通航口道路桥梁建设中,往往2条立交道路衔接高差非常大。一种新型螺旋式喇叭形互通立交具有克服大高差、增大匝道长度、减少纵坡、节约用地等特点。结合广东省虎门二桥项目海鸥岛互通立交的初步设计,具体分析了新型螺旋式喇叭形互通立交设计的一些方法和技术要求。

| Abstract: | There is large elevation difference between two interchange road in same mountain city bridges construction and ports bridges construction.A new spiral trumpet interchange has such advantages as dealing with the large elevation difference,increasing the ramp length,reducing the longitudinal,saving land and so on.Taking the primary design of Haioudao interchange in Guangdong province Humen 2ed Bridge project for example,this paper introduces several design techniques about this new spiral trumpet interchange. |
