3D Evaluation of Geological Environment Suitability of Underground Space Development in Suzhou Historic and Ancient Urban Area
Geological environment is the decisive factor affecting the development of underground space especially in historic urban areas with many constraints.It is important to evaluate the suitability of geological environment for the development of underground space.Considering the geological and historical environment of Guanqian district in Suzhou,13 evaluation indexes were selected and each combined weight was calculated based on the combination of analytic hierarchy process and entropy weight method.The evaluation results calculated by fuzzy comprehensive evaluation method were displayed in 3D visualization by ArcGIS.The results show that about 18.7％of the shallow underground space is suitable for development,59.1％of the shallow underground space is sub-suitable,21.2％of the shallow underground space is generally suitable,and only 1.0％of the shallow underground space is poor suitability.About 11.6％of the sub-shallow underground space is suitable for development,76.7％of the sub-shallow underground space is sub-suitable,11.7％of the sub-shallow underground space is generally suitable,and there is no space with poor suitability for sub-shallow underground space.
