General view of building foundation design practice against liquefaction is presented in this paper. The current practice in simplified procedures for evaluating soil liquefaction potential and the basics and methods of designing the building foundations by taking account the effect of the ground movement during soil liquefaction are also described. Two examples of building foundation design including liquefaction problems are introduced. One is an example of a building with pile foundation, where, the effect of the ground deformation during soil liquefaction was carefully considered. The other example is a building with a piled-raft foundation. In that case, the foundation soil was improved against liquefaction by lattice shape deep cement mixing method.
