Summary | Land liquefaction disaster hit the detached housing areas extensively by the Great East Japan Earthquake. In the process of recovery, however, there is almost no practical anti re-liquefaction technology that is able to implement to built-up areas with streets and houses in built condition. In order to support the local government as well as residents in the struck areas, NILIM did a large number of technical research and development within a short time since November 2012 to March 2013 such as development of easy calculation software for Downing Groundwater Level Method as well as Grillwork Underground Wall Method, conducting experiments on Vertical Drainpipe Method and Grillwork Underground Wall Method, performing three dimensional FEM analysis and so forth. |
