| 摘 要： | 近年来，城市活动断层的探测和研究工作在世界各地得到了迅速发展。查明活动断层的空间分布，确定断层的位置和最新活动时代，以便采取有针对性的防震减灾措施，已成为减轻地震灾害的一项极其重要的工作。地震反射波勘探是进行断层探测的重要物探手段，而对于一些地质环境复杂的地区，单纯的反射波勘探效果欠佳，因此提出了将反射波方法与基于初至波走时的层析成像技术相结合，充分利用地震资料，提高勘探的准确性。针对浅震在某工程地震勘探中的应用实例，归纳分析了该方法在本领域应用的技术特点、技术路线，探讨了该方法对于活动断层勘探的应用。

| Abstract: | In recent years，the detection and study of urban active faults around the world have achieved rapid development.Detecting the active fault location，depth and other geological information effectively，can avoid the damage of the construction on ground caused by active fault，and has been an important work to reduce the influence of strong ground movement.Shallow seismic reflection method is an important means of geophysical exploration to perform fault detection and fault activity analysis.For some areas of complex geological environment，a simple reflection exploration is ineffective，therefore，the authors proposed a method combined the reflection method with first-arrival travel-time tomography technique，which makes full use of seismic data to improve the accuracy of exploration.In this paper，aimed at the application examples in a strong earthquake engineering seismic exploration，the technical features and route of the method in this field of application were generalized，and the application of the method for active faults exploration was also discussed. |
