| Research Abstract |
This study focuses on time factor in remediation of coastal areas in Osaka Bay area asu as (1) combined failure of geotechnical structures due to Tsunami: progressive failure due to repeated arrivals of Tsunami, (2) pore water flow and pressure dissipation: progress of failure due to excess pore water pressure generation due to Tsunami and reduction effect on failure due to dissipation of pore water pressure, (3) mitigation measures and life cycle costs: progressive implementation of remediation measures. The results of the study lead to a methodology for evaluation of vulnerability in wide area and implementation of mitigation measures.
