Abstract: By the dynamic test, the dynamic properties of the silty sand of Hangzhou Qiangtang River flood protection levee are studied. The possibility of liquefaction is judged by the in-situ and laboratory tests. The liquefaction and dynamic stability are studied by adopting the Biot’s dynamic consolidation equation to do finite element analysis, which can consider the increasing as well as dissipating of pore water pressure during the earthquake. By the inverse analysis method, the acceleration at the basement rock obtained from free surface is inputted as seismic loading. The result will help us to understand the levee behavior during the earthquake intensity of 7 degree.

Key words: silty sand, earthquake, liquefaction, dynamic stability
