摘　　要：城市地下空间开发利用是我国城市发展的重要研究课题,如何实现城市强干扰环境地下地质结构“透明化”是科学、合理、安全开发利用城市地下空间的关键。我国地质环境条件复杂,特殊的地质构造给城市地下空间透明化带来了严峻的挑战。地球物理勘探的无损探测特点使其在城市地下空间探测中得到了广泛的应用。本文在介绍微重力探测、地质雷达、高密度电法、广域电磁法以及天然源面波勘探在城市地下空间探测应用的基础上,分析了不同地球物理探测技术在复杂地质背景下的应用效果及可行性,最后针对传统地球物理探测技术瓶颈提出了改进方案及建议,以期为城市强干扰环境地下空间透明化发展提供技术支撑。The development and utilization of urban underground space is an important research topic in China.How to realize the“transparency”of strong interference urban underground geological structure is the key to develop and utilize the urban underground space scientifically,reasonably and safely.The complicated geological environment and the special geological structure brings severe challenges to the development of urban underground space transparency in China.The non-destructive detection characteristics of geophysical exploration have made it widely used in urban underground space exploration.After introducing the applications of several geophysical methods in urban underground space,such as microgravity exploration,ground penetrating radar,electrical resistivity tomography,wide field electromagnetic method and the natural source surface wave exploration,this paper analyzes the application effect and feasibility of different geophysical exploration techniques in complex geological background and strong interference and finally puts forward improvement schemes and suggestions for the bottleneck of traditional geophysical exploration technology to provide technical support for the transparent development of urban underground space.
