【摘要】 在夏垫断裂上采用浅层纵、横波相结合的联合探测方法,获得了多条反映不同深度的高质量叠加时间剖面图,这些图像清晰地显示了夏垫断裂的浅部构造特征和地表以下浅至几米的地层结构和断裂特征信息,使得采用人工地震方法探测地表下10m以内的断裂成为可能。本次探测工作中,还在夏垫断裂的南侧发现了1条倾角较缓、呈铲型向下延伸的断裂,表明夏垫断裂是由2条断裂组成的断裂带。更多还原

【Abstract】 In the prospecting work,we obtain many high quality stack time sections that reflect different depth using Joint Shallow Exploration method of P and S waves on the Xiadian fault.These sections display clearly the shallow structure characteristics of Xiadian fault and the information of stratum structure and the fault characteristics within several meters below the surface.Artificial seismic method is able to prospect the fault within 10 m below the surface.In addition,a listric fault with gentle dip is found in the south of Xiadian fault in the prospecting work.The work gives us new knowledge that Xiadian fault is a fault zone consisting of two faults.更多还原
