Study on Pore Pressure and Liquefaction Behavior of Saturated Silt

This paper presents the test and research on typical silt conducted in Subei.It analysed the regularity of pore pressure and liquefaction behavior.The main purpose is to explore the liquefaction behavior affected by different factors.The liquefaction behavior of sand is discussed based on comparisons.The analysis resutts show that the higher the clay fraction,the greater of the liquefaction potential;and that the pore pressure will have different development trend under cyclic stress action.The authors proposed the model of pore pressure of the silt.
