Abstract: The ground fissure have changed geometric structure of strata,caused the earth physics field changed and destructed strata interface continuity,that provides the geology premise for 3D seismic exploring and surveying the ground fissure.Taking an example of the 3D seismic exploring and surveying the ground fissure in certain place the delta of Yangtze River,the paper clarified the problem of the 3D seismic data acquisition's method,the data processing,the data interpretation etc.,and obtained effective geology result.
