昆明联大立交方案选型研究

Study on Model Selection of Kunming Lianda Interchange Scheme

高速公路与城市道路相交的立交是立交设计中的难点。依托昆明联大立交方案的设计,统筹考虑立交设计时的规划道路、周边小区建筑、规划用地情况、占地大小、收费站布设及工程造价等方面问题,提出了5个设计方案。经过对5个方案的充分比较,形成了最终的设计方案。

The interchange intersected with expressway and urban road is a difficulty in the design of interchange. Based on the scheme design of Kunming Lianda Interchange, this paper completely considers the influences of planning roads, surrounding community architecture, planning land situation, land occupation size, toll station layout and engineering cost in the design of interchange, and puts forward five design schemes. After fully comparison of five schemes, the final design scheme is achieved.
