摘　　要：南京理工大学学生第十三宿舍桩机施工时 ,引起了轻亚粘土液化。通过对液化前后剪切波速的对比观测 ,对于 4种情况下的液化观测表明 ,随着液化程度的增加 ,剪切波速液化 (液化前 /液化后 )的比值也在增加 ,并增加到一定程度时变化值趋于稳定。When a pile machine was being operated for the foundation of thirteenth student's dormitory of Technical University of Nanjing, light subclay was liquated. Through the velocities of shear wave before and after liquefaction are contrasted, it is shown that the ratio of shear wave velocity before and after liquefaction increases with liquefaction developing, and then trends toward constance.
