城市隐伏活断层探测中采集参数的研究

根据波动方程有限差分原理，通过设定不同的观测系统参数，对浅层活断层模型进行正演模拟。同时结合实际资料，讨论适合于浅层城市活断层探测的采集参数。结果表明，采用小道距、小炮距以及适合于地震主频的数据采集方法可以得到高质量的浅层地震资料，有利于提高隐伏活断层上断点的定位精度。

Research of Acquisition Parameters in the Shallow Seismic Exploration of City Buried Active Fault

In this paper, we use the wave equation finite-difference method for forward modeling of the active fault model by setting different observation system parameters. Combining this with the application of practical urban active fault detection data, we obtain acquisition parameters that are suitable for shallow urban active fault detection. The results show that using the observation methods of small group intervals, mini-shot intervals and appropriate seismic frequency gets high quality shallow seismic data, which is conducive to improving the positioning accuracy of the breakpoint.
