城市多层隧道上层空间用作地下停车场设计研究

Research on the Design of Parking Lot in Upper Space of Urban Multi-Layer Tunnel

城市明挖暗埋隧道设计建造时,常采用多层结构形式,下层为行车空间,上层为空腔结构,如何针对隧道上层空间进行合理开发利用,国内外尚未有较深入的研究。本文基于厦门海沧海底隧道明挖段多层隧道,对隧道上层空间开发为地下停车场进行了探索,针对停车场平面设计、建筑设计、功能分区设计及防火分区设计等多方面进行理论研究,其设计理念与研究成果对合理开发利用城市地下空间,提高地下停车场的使用率,缓解城市停车压力具有重要意义。

Multi-layer structure is usually adopted in the design of cutting and covering tunnel, and the lower layer is the driving space while the upper layer is the cavity structure. How to rationally utilize the upper layer of tunnel has not been deeply studied at home and abroad. Based on the open-cut section of Xiamen Hai Cang tunnel, the scheme that the upper space of tunnel be developed into an underground parking lot is discussed. Theoretical research on the structural design, graphic design, architectural design, function and fre prevention design of parking lot is conducted. The design concept and research results are of great signifcance to the rational development and utilization of urban underground space, to improve the utilization rate of underground parking, and to relieve the pressure of urban parking.
