Geological suitability evaluation of underground space is a critical condition for the development and utilization of urban underground space resources.Because of the unique characteristics of coastal plain cities,a particular geological suitability assessment approach is required to guide the geological suitability evaluation of underground space.Using Rizhao City as the research site,this work thoroughly examined the geological environment factors influencing underground space development and proposed an evaluation index system of coastal plain urban geological suitability based on basic geology and constrained geological conditions.The empirical score technique,entropy weight method,and comprehensive assessment model were used to determine the geological suitability zoning of shallow(0～15 m)and sub-shallow(15～30 m)subterranean space in the research region.Results indicate that the geological suitability of underground space is significantly influenced by the depth of water table,fault zones,land subsidence,and seawater intrusion.About 90%of the study region belongs to shallow and sub-shallow subterranean spaces,which are mainly suitable and relatively suitable.Approximately 10%of the research area is comprised of the inappropriate area.
