GIS-BASED QUALITY EVALUATION OF UNDERGROUND SPACE RESOURCES IN YANGTZE RIVER DEMONSTRATION DISTRICT OF WUHAN CITY

The underground space development is a hot spot in urban construction currently. To serve the planning and construction of underground space in Yangtze River Demonstration District of Wuhan City, based on a large number of basic data and results obtained from multi-factor urban geological survey, combined with GIS technology, the paper carries out the underground space resources quality evaluation of the study area, which is shown in the zoning map of underground space resources quality of different depths. The results indicate that the quality of shallow and sub-shallow underground space resources are generally good-excellent, with the southwest side obviously inferior to the east and north sides, mainly affected by the existing underground structures, soft soil and groundwater. The quality of sub-deep and deep underground space resources are generally medium-good, mainly affected by the development depth, karst and rock excavation difficulty.
