Interpretation of the Overburden Pressure Effect on Sand Liquefaction Behavior
Publication: Geo-Congress 2023
ABSTRACT
This article studies the effect of overburden pressure on liquefaction behavior of saturated Ottawa F65 sand using centrifuge experiments as well as numerical simulations. A series of centrifuge tests were conducted simulating a 5 m layer of Ottawa sand having different relative densities and subjected to overburden effective pressures of 1 atm and 6 atm. The objective was to study the pore pressure response of sand to base acceleration under low and high overburden pressure. The sand layer had a bottom impervious boundary and a top pervious boundary, approximating an idealized field condition. The analysis shows that sand during liquefaction is not fully undrained but rather partially drained. It was also found that partial drainage was more significant at 6 atm than at 1 atm due to the increased coefficient of consolidation, cv at higher overburden pressure.
