Study on Seismic Damage Mechanism of Dredger Fill Ground in Tianjin Binhai Area

Tianjin binhai new area has a large of dredger fill groud, And it is easy to produce seismic settlement and saturated sand liquefaction under earthquake action. We simulate subsidence state Dredger Fill the 50-year probability exceedance 10% 2% level by using Finn constitutive model in certain soft foudition area. The results show that: Both are transition process from effective stress pore water pressure. Moreover, soil stronger shallower buried depth more likely collapse liquefaction.
