Improving the Accuracy of Liquefaction Damage Estimation Method for Infrastructure Facilities Using Three-Dimensional Ground Structure Model

Abstract

National Institute for Land and Infrastructure Management （NILIM） by Ministry of Land, Infrastructure, Transport and Tourism （MLIT） is planning to consider prioritization and priority evaluation of liquefaction measures for the network of infrastructure facilities and prepare liquefaction hazard maps for infrastructure facilities. for that purpose, we created a three-dimensional ground structure model for actual districts experimentally that the complexity of the distribution of ground and geological features and the ground property which cause liquefaction damage are reflected. On the basis of this model, we examined a method for highly accurate prediction of liquefaction damage.
