Suitability Evaluation of Underground Space Exploitation: a Case Study of Changjiang New Town in Wuhan

The suitability should be fully considered before the exploitation of urban underground space. Taking Changjiang new town in Wuhan as an example, this paper puts forward the suitability evaluation model of "suitability = resource quality × exploitation demand", in addition, it introduces the evaluation method and index system of underground space resource quality and exploitation demand. And then combined with the results of the multi-element urban geological survey and master plan of Changjiang New Town, the corresponding evaluation zoning map is obtained through the evaluation of underground space resource quality, exploitation demand and suitability. Finally, through the analysis of the evaluation results, the author expound the characteristics of the resource quality, exploitation demand, and suitability, and put forward suggestions for the exploitation of underground space. The research results can not only effectively serve the planning and construction of the underground space of the Changjiang New Town, but also establish a complete evaluation system of suitability evaluation, which has important theoretical and practical guidance.
