摘要：
For unfree ground with existing building, the sandy soil liquefaction potential under earthquake is studied by using numerical dynamic response analysis. The influence of building stiffness, width and building weight on liquefaction zone distribution is investigated through various conditions of calculation. In conventional cognition, the sand under building is difficult to liquefy. However, it is demonstrated by this numerical calculation that the actual situation may not always be always so simple. A zone with the shape of character V under building shows high potential of liquefaction, and is closely related to the building stiffness, width and building weight.
