Abstract

A new method to estimate an accurate surface layer model is proposed for hilly area where the data on artificial transformation on ground is not sufficient. This method considers the distribution of surface layers and artificial transformation based on the topographical and geographical features on pre-transformed ground, which are newly evaluated by the aerial photographs on 1930's. Initial model for the 3-D surface layer structure is estimated based on the evaluated high-resolution map of landfill distribution, change of geomorphological land classification, and existing drilling data. Then the Vs profile for each site is revised by the dispersion curves evaluated by the array observation of microtremor. The accuracy of the method is confirmed at the Nagoya University campus by use of the observed seismic records. The presented method is effective for hilly areas where the heavy land transformation has been performed.
