Abstract: The development and utilization of underground space have become the tendency for city construction, and in such cases, urban geological condition is decisive in the development and utilization of underground space in safety and economy, when the development and utilization of urban underground space are restricted by the key geological factors. Based on the researching of regional geology, geological structure, seismogeology, groundwater and surface water, properties of special rock and soil, the adverse geological actions and geological disaster, the influencing grade of geological conditions to the development of urban underground space in Yueyang city are discussed. And then the suitability zoning of urban underground space had been catalogued to 4 parties such as perfectly suitable region, suitable region, poor adaptation region and inferior region. It can provide geological basis for the preliminary planning and decision making of the underground project in Yueyang city.
