城市地下互通立交方案设计的研究与应用

Research and Application of Design Schemes for Urban Underground Interchange

城市地下互通立交的规划设计是一项复杂的系统工程,需要综合考虑城市地下道路系统的转换功能及需求、地形地貌、地质条件、交通安全、结构安全、防灾救援等多种因素。基于城市地下互通立交的建设发展需求,从对地下互通立交的特点入手,总结了地下互通立交的设置条件、关键技术指标及关键技术应用,结合深圳侨城东路工程实践进行佐证,进一步论证了地下互通立交工程的可行性及运行安全。

The planning and design of urban underground interchange is a complex system engineering,which need to comprehensively consider the multiple factors of functional conversion and demand,terrain and topography,geological conditions,traffic safety,structural safety,disaster prevention and rescue of urban underground road system.Based on the construction development needs of urban underground interchanges,according to the characteristics of underground interchange,the setting conditions,key technical indicators and critical technical applications of underground interchange are summarized,and are proved by the practice of East Qiaocheng Road Project in Shenzhen.The feasibility and operational safety of underground interchange projects are further demonstrated,which can be referred for the follow-up construction of underground interchange projects.
