为了获得适合于在大城市开展地震反射探测工作的参数和施工方法,在银川市进行了城市活断层探测方法试验。试验内容包括地震波激发参数试验、观测系统参数试验和地震反射资料处理方法试验。并在各种参数试验和资料处理方法试验的基础上,采用通过试验所获得的工作参数和方法,在银川盆地内开展了城市活断层探测试验,试验获得了银川盆地深浅部构造的清晰图像。
In order to obtain the parameters and construction methods suitable for seismic reflection detection in large cities, the urban active fault detection method test was conducted in Yinchuan. The test includes seismic wave excitation parameter test, observation system parameter test and seismic reflection data processing method test. Based on the experiments of various parameters and data processing methods, the urban active fault exploration test was carried out in Yinchuan Basin by using the working parameters and methods obtained from the experiment. The clear and deep images of the deep and shallow structures in Yinchuan Basin were obtained.
