Detailed Study of Near Surface Resonance Properties Using Low Channel Microtremor Measurements - Physical Modelling Data

The method for detailed study of resonance properties of near-surface section using low channel microtremor measurements was tested on three-dimensional physical model with known characteristics. The model of layer overlying the vertical boundary of two mediums was investigated. It is shown that for measurements made with low-channel equipment and relocatable receivers the conversion of nonsimultaneous data to “common” time using synchronous data from fixed receiver can improve considerably the results of seismic microzonation. Experimental results are in good agreement with the data of finite element simulation.
