摘　　要：为解决复杂控制条件下山区高速公路互通立交选址、方案等设计问题,通过多方案综合分析和工程案例分析的方法,深入分析了深V峡谷区地势陡峭、地质复杂、桥隧构筑物多,与现有道路之间落差大,以及场地狭小等复杂控制条件下对巫镇高速公路互通立交规划设计的影响,同时提出相应的设计策略和优化措施:1)合理选址、选型;2)灵活采用技术指标;3)多方案综合比选等。结果表明,以上措施在巫镇高速公路互通立交设计中的应用,显著提高了互通立交的安全性和通行效率,减小了工程规模,说明在复杂控制条件下科学合理地进行互通立交的选址和布设的可行性。该研究结果可供同类工程参考。To solve the design problems of mountainous highway interchange location and scheme under complex control conditions,the impact of complex control conditions such as steep terrain,complex geology,multiple bridge and tunnel structures,large drop between existing roads,and narrow and small sites on the planning and design of the Wuxi-Zhenping Expressway interchange was deeply analyzed,through comprehensive analysis of multiple schemes and engineering case studies.At the same time,corresponding design strategies and optimization measures were proposed,which are reasonable location and selection,flexible use of technical indicators,and comprehensive comparison and selection of multiple schemes.The results showed that the application of the above measures in the design of the Wuxi-Zhenping Expressway interchange significantly improved the safety and traffic efficiency of the interchange,reduced the scale of the project,and demonstrated the feasibility of scientific and reasonable selection and arrangement of the interchange under complex control conditions.This research result can be considered for similar projects.
