三道贯通即慢行通道贯通,是上海黄浦江两岸公共空间开放的重点。虹口滨江段的慢行通道贯通的难点在于,贯通的设计及实施是基于现状城市商业功能区、北外滩滨江绿地的改造,而非新建。本文重点阐述慢行通道在上海虹口滨江公共空间贯通建设工程中的应用,包括慢道贯通设计理念、遇到的问题、针对问题的解决策略等。 Three through that slow passage through, Shanghai Huangpu River is the focus of open public space. The difficulty with which the slow passage of Hongkou Binjiang section runs through lies in that the design and implementation of Tongjiang is based on the reconstruction of the status quo of the urban commercial functional area and the renovation of the north bank’s waterfront greenbelt instead of the new construction. This article focuses on the application of the slow passage in the construction of Shanghai Hongkou Riverside Public Space Project, including the design concept of slow passage, the problems encountered and the solutions to the problems.
