摘　　要：为查明合肥市地下空间开发的地质环境制约因素及地下空间开发中需注意的地质问题,以野外地质调查、钻探、室内测试等手段获得的原始数据为基础,研究合肥市地形地貌、工程地质条件、水文地质条件、活动断裂等地质因素的发育分布特征及其对地下空间开发可能造成的影响,并提出合肥市地下空间开发利用的对策与建议。结果表明:地形地貌、工程地质条件、水文地质条件、活动断裂是影响合肥市地下空间开发的主要地质因素;合肥市总体地质条件较好,利于地下空间开发,部分地区地下空间开发利用需注意地形坡度、膨胀土、软土、承压含水层、活动断裂等因素的影响。为政府部门编制城市地下空间资源开发利用规划提供地质依据,为实现合肥市地下空间资源的可持续发展提供参考。In order to find out the geological environment constraints and the geological problems in the development of underground space of Hefei,based on the original data by means of geological survey,drilling and indoor test,this paper studied the geological factors such as landform and geomorphology,engineering geological conditions,hydrogeological conditions and active faults.The paper puts forward the countermeasures and suggestions. The results show that topographic landforms,engineering geological conditions,hydrogeological conditions and active faults are the main geological factors in the development of underground space in Hefei.The overall geological conditions in Hefei are good for the development of underground space,and the development and utilization of underground space in some areas should be paid attention to especially shape slope,expansive soil,soft soil,artesian aquifer and active faults. Research results provide a geological basis for the development and utilization of urban underground space resources to the government,and a useful reference for the sustainable development of underground space resources in Hefei.
