SUN Heng-chu, ZHOU Xiao-wen, CAI Yuan-lin. Numerical simulation of sandy soil liquefaction zoneing for unfree field under earthquake[J]. 2007, 28(S1).DOI:
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
