| Abstract: |
The emergence of new technologies is largely dependent on critical examination of the current state of relevant technologies. Accordingly, this paper aims to present the latest advancements in the issues related to deep-mixing technology when applied as a countermeasure against liquefaction. Various remedial measures based on the solidification concept are discussed. The basic issues related to various applications of deep mixing for liquefaction, design considerations, and seismic response analysis are examined. A number of case histories is presented, along with the latest progress in new pertinent technologies currently under investigation in Japan. A conceptual framework is proposed for liquefaction mitigation of existing structures. The research needed for further investigation using deep-mixing technology for liquefaction is summarized. |
