| Outline of Final Research Achievements |
A method of interpolating and estimating two-dimensional earthquake motion transfer function on sedimentary ground surface with inclined base layers was developed, by one-dimensionally obtaining earthquake motion transfer functions from the ground model at the top and bottom of the inclined base layers surface in the irregular-shaped early stage and superimposing them. By using this method, it becomes possible to analyze ground motion on inclined base layer using the input data of the ground motion analysis method such as the equivalent linearization method which has been done as it is, and it is possible to analyze the ground motion is extremely easy. Earthquake and liquefaction hazard maps were created for specific topography, and it was found that usability was improved as compared with the map based on the conventional method.
