At 10 measurement points along the same survey line, observations were conducted using various array types such as double circular array, cross shaped array, and linear array. Then, we extracted dispersion curves, plotted apparent S-wave velocity profiles. The study obtained the following two results. Firstly, the apparent S-wave velocity profiles obtained from cross shaped array are basically consistent with those obtained from double circular array, and the delineated interfaces of geological layers are also generally consistent, but there are differences in the positions of velocity anomaly bodies delineated by the two types of arrays. Secondly, there are significant differences between the apparent S-wave velocity profiles of the linear array and the double circular array, and there are significant differences in the apparent S-wave velocity profiles obtained from the linear array with different orientations, as well as in the division of the soil rock interface. When conducting microtremor exploration, double circular array should be prioritized, cross shaped array should be used depending on the situation, and linear array should be used with caution.
