【摘要】 近十年来,在城市地下空间开发利用中,由于建筑物阻隔与强干扰影响,既有地球物理勘探技术应用过程中遇到了实施过程困难、数据质量低、勘探精度等难题,尤其在房屋密集区的勘探中困难重重,甚至出现勘探盲区。本文系统地总结了复杂城市环境的勘探技术,在阐述密集空间和抗干扰两个方面的探测技术进展的基础上,介绍了多源地震勘探技术的研究进展。展望未来,以科学问题为导向,利用以新通讯技术和新传感器材料为基础的微动谱比技术、密集台阵微动测技术、光纤声波传感技术等多种地面地球物理探测技术是复杂城市环境下勘探技术的方向。开展多源地震勘探、联合反演和成像,并提取研究对象的综合横波速度正日益成为提高城市复杂环境下地球物理勘探的有效途径,具有广阔的应用前景。更多还原

【Abstract】 In recent ten years, due to the barrier of buildings and strong interference, the application of existing geophysical exploration technologies has encountered various difficulties in implementation, low data quality and exploration accuracy, especially in the exploration of densely populated housing areas, some even bump into exploration blind areas. This paper systematically reviewed the exploration technology of complex urban environment, the research progress of multi-source seismic exploration technology and the development of exploration technology in dense space and anti-jamming issues. Looking forward to the future, guided by scientific thinking, utilizing various ground geophysical exploration technologies such as microdynamic spectrum ratio technology, new communication technologies-based and new sensor materials-surpported, dense array-based microdynamic measurement technology and optical fiber acoustic sensing technology will be the exploration technologies in complex urban environments. The comprehensive S-wave velocity of multi-source seismic exploration, joint inversion and imaging and extraction of research objects are becoming effective ways to improve geophysical exploration in complex urban environments with broad application prospects.更多还原
