On profile design of interlinked flyover

简要归纳了互通立交纵断面设计难点,分析了互通立交设计的影响因素,并从转移路拱的设置、匝道端部标高确定等方面对立交纵断面设计进行了阐述,对公路建设具有重要意义。

The paper sums up the design difficulties for the profile of interlinked flyover,analyzes the influential factors for the design of interlinked flyover,and illustrates the design for the flyover profile from the allocation of transferred road camber and the identification of the end elevation of ramps,so as to be meaningful for the road construction.
