摘要
结合鄂尔多斯盆地北部塔巴庙地区低、降速带的调查实例,简述多道面波分析 MASW在沙漠地区的应用,并将反演结果与小折射资料进行对比说明其运用效果。实践表明,在采集和处理参数选取合理的情况下,最大勘探测度可以达60 m,完全可以满足实际工作需要。在近地表构造复杂地区采用多道面波分析技术进行低、降速带情况调查,可以弥补小折射和微测井调查的不足,展现出受地表环境影响较小的优越性。
We present here a case study of investigating the low-depression velocity in Temple of North Taba Area in Erdos Basin. The MASW method successfully defined the low-depression velocity layer in the desert area. Comparing results obtained by the MASW method with results by refraction seismic method, we discussed efficiency and simplicity of applying the MASW method in the desert area. It is proved that the maximum investigation depth can reach 60m in the area when the acquisition and procession parameters are carefully chosen. The MASW method can remedy the incompetence of the refraction method and the micro-seismograph log method in low-depression velocity layer’s investigation.The MASW method is also a powerful tool in investigation of near-surface complicated materials and possesses many unique advantages.
