摘　　要：结合现状建设条件、路网规划及交通量预测,确定立交功能定位,分析立交匝道落地点位置,提出G107与四环线“双喇叭”“单喇叭+T形”2个立交方案。通过对比,确定“单喇叭+T形”立交方案为推荐方案,即由G107国道高架层引出4条匝道,接入四环线长青收费站,与现状单喇叭立交形成组合式立交。Based on the current construction conditions,road network planning&traffic volume prediction,the function positioning of the interchange is determined,the on-ramp landing location of the interchange is analyzed,and two interchange schemes of double horn&single horn+T-shaped are proposed for G107 and the Fourth-Ring Road.By comparison,it is determined that the single horn+T-shaped interchange scheme is the recommended scheme,that is,four ramps are led from the elevated level of G107 National Highway and connected to the Changqing Toll Station of the Fourth-Ring Road,forming a combined interchange with the current single horn interchange.
