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