摘　　要：某地下综合交通枢纽施工,包括地下四层车站结构与地下行车隧道。由于地铁限界原因,部分行车隧道无法采用板柱体系支撑,半悬挂地下车道结构因其释放下部空间,增大净空同时施工便捷等优点,被应用于地下综合体行车道施工。由于地下综合体为盖挖逆作施工且结构复杂,影响因素众多。本文依托深圳黄木岗地下综合交通枢纽工程,结合施工现场实际情况,基于数值分析结果重点阐述半悬挂地下车道设计要点、施工工艺与质量控制措施,对今后类似地下车道施工提供一定参考价值。Construction of an underground integrated transport hub, including the structure of the four-storey underground station and the underground road tunnel. Due to the subway limits, some road tunnels can not be supported by a column system, semi-suspended underground lane structure because of its release of lower space, increase clearance while construction convenience, etc., is applied to the construction of underground complex lanes. There are many influencing factors because the underground complex is the construction of the cover excavation reverse and the structure is complex. This paper relies on the Shenzhen Huangmugang underground integrated transportation hub project, combined with the actual situation of the construction site, and focuses on the design points, construction technology and quality control measures of the semi-suspended underground lane based on the numerical analysis results, which provides a certain reference value for the construction of similar underground lanes in the future.
