摘要
作为出行最集中的城市核心区,人车干扰严重、停车矛盾突出,为解决这些问题,地下环路应运而生。因地下环路不可逆、投资大,应最大限度提高其利用率。在规划层面,影响利用率的主要因素有环路长度、出入口数量及其设置情况。通过梳理国内外相关案例,进行案例总结分析;以及研究相关文献及规范,进行理论验证分析。建议地下环路单环长度不大于1km;单向2(3)车道地下环路的外部出入口数量宜为3对/km或3对/环(4对/km或4对/环),应不少于2对/km或者2对/环(3对/km或者3对/环);连接地下环路与地下车库间的出入口数量宜为外部出入口的1.5~2.5倍。
As the most concentrated hub for commuting,the urban core area faces challenges of congestion and parking conflicts.To address these issues,the underground ring road comes into existence.Due to the irreversibility and substantial investment of constructions,underground ring roads should be designed to maximize their utilization.In planning,the main factors influencing utilization rates include the length of the ring road,the number and configuration of gateways.Through a review of relevant cases across China and other countries,this paper summarizes case studies and reviews pertinent literature and specifications to conduct a theoretical analysis for validation.The present research proposes that the length of a single ring for the underground ring road should not exceed 1 kilometer.The number of external gateways for a one-way 2 lane(3 lane)underground ring road is suggested to be 3 pairs/kilometer or 3 pairs/ring(4 pairs/kilometer or 4 pairs/ring),with a minimum of 2 pairs/kilometer or 2 pairs/ring(3 pairs/kilometer or 3 pairs/ring).The number of gateways for the underground garage connected to the underground ring road should be 1.5 to 2.5 times that of the external gateways.
