Title: Experimental study of earthquake liquefaction of saturated silt in Tianjin area
Abstract: The soil liquefaction caused by earthquake is one of the direct reasons for the foundation invalidation and the structure collapse.Based on in-situ tests,liquefaction estimation of silt with different origins in Tianjin area is studied.Then the dynamic properties and liquefaction mechanism of the silt were illuminated based on dynamic triaxial test.And a comparison between the existed earthquake liquefaction assessment methods was made.combined with the in-situ tests.It is suggested that the influence of silt content should be taken into account in the liquefaction assessment;and the value of pore water pressure is 60%-90% of confining pressure,the value of double amplitude strain is 4%,these values can be used as the indexes of liquefaction evalution.
