摘要: 随着中国经济的快速发展和城市化进程的加快，有限的土地资源和城市发展之间的矛盾越来越突出，城市地下空间的安全、合理利用和地质环境保护具有重要的战略意义。为了解决G20、亚运会以及数字经济为杭州市快速发展带来的人口快速增长与土地资源有限的瓶颈问题，针对以杭州为代表的南方丘陵地区地下空间精细探测需求，开展了弹性波法、电法与电磁法等多种地球物理方法的可行性研究。结果表明：不同勘探方法在探测深度、分辨率以及勘探效率上具有明显的差异性，需要根据地下地质状况以及地表条件选择合适的勘探方法进行探测，这对类似丘陵地区城市地下空间开发及利用具有指导意义和参考价值。Abstract: With the swift growth of China's economy and the acceleration of urbanization, the contradiction between limited land resources and urban development is becoming more and more salient. Hence, the safe and rational use of urban underground space and geological environmental protection are of great strategic significance. The G20, Asian Games and digital economy bring great opportunities for the rapid development of Hangzhou, but also cause a thorny bottleneck between rapid population growth and limited land resources. In order to solve this problem, School of Earth Sciences of Zhejiang University has carried out a feasibility study of a variety of geophysical methods, including elastic wave methods, electrical and electromagnetic methods, in view of the need for detailed detection of underground space under this special geomorphological geology in the hilly area of south china. The results show that different exploration methods have obvious differences in exploration depth, resolution and exploration efficiency, so it is necessary to select suitable exploration methods according to underground geological conditions and surface conditions. These conclusions will have exemplary guiding significance and reference value for the development and utilization of urban underground space in the southern hilly area.
