摘　　要：目前用于城市活断层调查的主要地球物理方法为反射地震方法。由于在城市勘探中,遇到的各种干扰因素很多,研究这些干扰的特征,并采取相应的方法技术是开展城市活断层浅层地震勘探的关键。根据近几年来城市活断层调查的工作实践,通过典型实例阐述了如何根据不同城市复杂的工作环境、地震地质条件和要求解决的地质问题,合理选用工作程序和方法技术的工作经验。Seismic reflection method has been one of the main geophysical methods for detection of active faults in urban areas at present. The key point to carry out the shallow seismic surveys is to understand characteristics of interferences commonly encountered in cities and adopt corresponding measures to suppress them. Based on our experiences of years, the reasonable field procedures, in view of complicated environments and specific seismic and geologic conditions in cities, have been summarized.
