Abstract

This paper discuss the new subjects of the liquefaction research seen to liquefaction damage of the Great East Japan Disaster. Specifically, the subject about the liquefaction potential assessment, the subject about the evaluation of ground subsidence caused by liquefaction and the subject seen to the liquefaction damage of a river levee, etc. are discussed based on the damage observed or the experimental result. It was shown that understanding present damage on the extension of the present technology has a limit, and that the prediction and countermeasure technology of the liquefaction damage based on a new concept is necessary.
