摘要
当前快速城市化与城市地下空间开发给浅层地震勘探技术的发展带来了挑战和良好机遇。笔者从地震勘探仪器设备、数据采集、数据处理和解释应用等方面介绍了近年来城市浅层地震勘探技术所取得的主要进展,包括陆上地震拖缆系统的研发、无线地震数据采集、可控震源伪随机扫描方法、城市噪声面波勘探技术及地震数据综合处理算法等。结果认为,通过瑞雷波约束折射P波层析成像结果或联合反演方法,可以提高后者对城市地下"百米"空间的探测精度;利用城市噪声作为震源,既能获得对描述浅层地质特征有重要意义的补充信息,同时又满足了城市对绿色、环保震源的要求;而陆上地震拖缆系统则使得S波技术在城市地下浅层勘探中可以发挥更加重要的作用。今后发展建议:一是加强城市浅层地震数据采集关键技术装备的研发;二是进一步开发和完善非传统(如面波)地震勘探方法,深入挖掘地震波中所蕴含的大量有用信息。
The current rapid urbanization and underground development have brought challenges and good opportunities for the development of shallow seismic exploration technology.In this paper,the main advances made in shallow seismic exploration in cities in recent years have been introduced in terms of seismic exploration equipment,data acquisition,data processing,interpretation and their applications,which include the development of seismic land-streamer systems,wireless seismic data acquisition,vibroseis pseudo-random sweeps method,urban noise surface wave exploration technology and comprehensive data processing algorithms. Some conclusions have been reached： the Rayleigh wave constrained refraction P-wave tomography results or the joint inversion method can improve the accuracy of detection of urban underground ＂ 100-meter＂ space; using urban noise as a source,it can not only provide supplementary information that is important for the description of shallow geological features,but also meets the city＇s requirements for green and environmental protection; through the seismic land-streamer system,S-wave technology can play a more important role in urban shallow exploration.Some proposals for future development are put forward： First,to strengthen the research and development of key technologies and equipment for shallow seismic data acquisition in urban area; Second,to further develop and improve non-traditional（ such as surface wave）seismic exploration methods,and to dig deeply into a large amount of useful information contained in seismic waves.
