Research on the Criterion of Planning Classification for Urban Underground Space

The research on the criterion of planning classification is the important technical foundation of weaving, researching and administering for urban underground space planning. With more attention paid to the planning and construction of urban underground space, the absence of classification criterion is affecting the healthy development of urban underground space, and the research and weaving of classification criterion is more and more necessary. With the analysis of the actual practice and research of urban underground space, this paper investigates the inbeing of urban underground space at first, probes into the demand of urban underground space planning system to the classification criterion, brings forward the classification principles and means of the urban underground space, establishes the two-level urban underground space classification system with seven chief categories and 25 mini-categories, and constitutes the codes for these categories. All these work is the primary groping for the instauration and consummating of the urban underground space criterion system.
