| Abstract: | Liquefaction potential is evaluated using both in-situ and laboratory testing methods. Liquefaction and dynamic stability for the levee are determined using Biot’s dynamic consolidation equation which is used to analyze the increase and dissipation of pore water pressure as well as liquefaction and dynamic stability in the levee during a magnitude 7 earthquake. By inverse analysis, the acceleration at the bedrock is obtained from the acceleration data monitored previously at free surface and is inputted as the seismic loading. Results presented in this paper can provide improved stability assessment for levees experiencing seismic events of this magnitude. |
