该文以南盘江表层结构调查为例 ,论述了综合物探方法在表层结构调查中的应用。利用陆地声纳法与微分电测深法 ,可有效地划分出低速带、降速带的厚度和速度 ,其结果与微地震测井成果吻合。
Taking Nanpanjiang surface structure survey as an example, this paper discusses the application of synthetic geophysical methods in surface structure investigation. Using the land sonar method and the differential electric sounding method, the thicknesses and velocities of the low-velocity belt and the decelerated belt can be effectively distinguished. The results are in good agreement with those of the microseismic logging.
