浅谈我国城市地下快速路地下互通立交研究及发展

Brief Discussion on Research and Development of Underground Interchanges on Underground Expressways in China

摘要:

随着城市地下道路逐渐呈现网络化发展趋势，地下互通立交应运而生。对地下互通立交的选型、通行能力、平纵横线形、分合流端部结构研究及实践进行总结分析，完善分析地下互通立交的特点，初步提出地下快速路地下互通立交的适用性。结合建设案例的调研，对建设案例的经验和创新点进行了总结分析，提出城市地下快速路地下互通立交规划及设计的控制性建议，以期为我国城市地下快速路地下互通立交的研究发展提供初步参考。

Abstract:

With the gradual trend of networked development of urban underground roads, underground interchanges have emerged. The research and practice in the selection, traffic capacity, horizontal and vertical alignments, and dividing and merging end structures of underground interchanges are summarized and analyzed. The characteristics of underground interchange are perfected and analyzed. The applicability of underground interchanges on underground expressways is initially proposed. Combined with the research of construction cases, the experience and innovation points of the construction cases are summarized and analyzed, and the controlling suggestions for the planning and design of underground interchanges on urban underground expressways are proposed in order to provide the preliminary reference for the research and development of underground interchanges on urban underground expressways in China.
