在道路下方建设隧道形式的立体车库，并将隧道式立体车库与综合管廊结合，既能解决城市停车难问题，也能够更充分利用地下空间。提出将综合管廊与地下立体车库结合，并综合分析路下隧道式立体车库的建筑方案、结构组成、建造方法、运行流程及未来的发展，得到以下结论： 利用地下空间增建路下隧道式立体车库，路面上仅保留地上出入口，占用一小块地面空间建设地下立体车库，可以进一步解决目前存在的停车难问题；采用顶管、盾构等机械自动化建设方案，对已有道路结构及周边环境影响较小，对道路通行能力影响较小，且始发井/接收井可用作立体车库的升降通道，进一步提高地下空间利用率。在国家兴建地下综合管廊的同时修建地下车库，将二者合二为一，既能够解决社会问题，也能够节省工期和成本，对城市建设具有重大意义。

The stereo garages under road combined with utility tunnels can solve urban parking problem and make full use of underground space. In this paper, the combination scheme of the utility tunnels and underground stereo garages is proposed, and the construction scheme, structural composition, construction method, operation process, and future development of the tunnel type stereo garage under the road are comprehensively analyzed. Some conclusions are drawn as follows. (1) The tunnel type stereo garage under road with an entrance/exit on ground only occupies a small land on ground to solve urban parking problem. (2) The mechanical automatic construction scheme by pipe jacking or shield has little influence on the existing road structures, surrounding environment, and road running capacity; the launching/receiving shafts constructed can be used as the lifting channel to further make full use of underground space. The combination of utility tunnels and underground garages has many social benefits such as cost reduction, and is beneficial to urban development.
