青岛市地下道路规划发展设想

Planning assumption about Qingdao underground roads

城市人口的膨胀和机动车的迅猛增长导致很多城市出现了交通拥堵,开发利用地下空间可以分流地面交通,改善交通运行状况。在对国内外典型城市地下道路规划建设经验借鉴的基础上,提出青岛市未来地下道路布局可以采取点状、脊状以及环状模式,并分析了各种模式的适用性。在布局模式的基础上,结合青岛地形、地貌特点,提出了未来再增加跨海通道的规划设想,规划了穿越太平山、老虎山、浮山等山体的地下道路,改善青岛目前东西不畅、南北不通的交通状况,建议尚未实施的快速路研究建设地下道路的可行性,并且在交通量较大的区域和交叉口实现主线下穿,提高交叉口的通行能力。

The rapid growth of city population and motor vehicles has caused traffic jam.The development and utilization of underground space can shunt ground traffic and improve traffic conditions.The paper put forward that Qingdao underground roads could take punctate mode,ridged mode and annular mode on the basis of the typical underground road planning and construction experience at home and abroad.On the basis of layout mode,the planning assumption of the sea channel was proposed auording to Qingdao landform.And at the same time underground roads of passing Taipingshan Mountain and Laohushan Mountain Fushan Mountain were planned.These underground roads could improve the traffic condition of Qingdao east-west and south-north.The feasibility of unconstructed expressway and underground roads is suggested to be studied and feasibility of underground roads and the main roads through crossing is realized to improve intersection capacity at the heavy traffic area.5figs,10 refs.
