Abstract：We have completed some application experiments by the MSM on Jianghan Plain and the Yangtze levee. The results show that the dispersion curve is more stable from the SPAC than the F-K method. We can get the 1-D underground structure information from several meters to hundreds of meters by transferring the size and geometry of the recording array. The 2-D and 3-D structures of the earth can be obtained by translating these results. Due to its merits of passivity, non-invasiveness and strong adaptability to the environment, the MSM has important application values in the field of earthquake engineering and engineering geophysical exploration in urban areas.
