摘要
为了提高渝蓉高速公路与重庆绕城高速公路交叉处渝西枢纽互通式立交的服务水平,满足各方向车流快速、高效、安全转换的需求,根据立交周边地形地貌和城市规划等限制条件,对各阶段不同立交方案分别从交通和环境适应能力、行车安全、工程造价等方面进行多方案比选、优化后,最终推荐技术可行、经济合理、符合驾驶习惯的"变异Y形+变异喇叭形"设计方案,为今后类似枢纽互通式立交的设计提供参考。
In order to improve the service of Yu Xi pivot interchange at the junction between Yu Rong expressway and Chong Qing outer circular expressway, and to meet fast, efficient and safe transition in each direction, this paper recommends a ＂variable Y type＋variable trumpet type＂ interchange proposal, according to the restricted conditions such as the surrounding landscape and urban planning. The proposal proves to be feasible, economical and conform to driving habits with respect to traffic and environmental adaptability, safety and cost based on scheme comparison and optimization of different interchange plans. It may provide references for future similar interchange design.
