[Objective]Xiongan New Area of Hebei Province is a city to be built soon.To ensure the geological safety of the planning and construction of the new area,the suitability evaluation of the Xiong'an New Area engineering construction is carried out.[Methods]A customized evaluation index system for the suitability of engineering construction has been developed based on the geological conditions of Xiong'an New Area and in alignment with the millennium plan for planning and construction.The evaluation of engineering construction suitability in Xiong'an New Area was conducted using a multi-factor graded weighted index sum method.[Results]The engineering construction suitability in Xiong'an New Area is favorable,with both suitable areas covering 925 km2 and relatively suitable areas covering 845 km2.The more suitable areas are primarily located in the central and southern parts of the research area,while other areas are classified as suitable.Some parts of Xiong'an New Area face environmental geological challenges such as ground subsidence,sand liquefaction,soft soil,soil and water pollution,soil and water corrosiveness.These environmental geological issues directly impact the overall evaluation results,although they do not completely rule out the feasibility of construction in the comprehensive evaluation.[Conclusion]A comprehensive parameter system has been developed for evaluating the suitability of engineering construction in Xiong'an New Area.The evaluation factors have been quantified,reasonable weight values have been determined,and a geological survey evaluation method system has been established.The system is designed to serve national spatial layout,engineering construction and underground space development,offering valuable insights for relevant urban planning and construction.
