Abstract

Various researchers have published results regarding the effect of non plastic silts on the liquefaction behavior of sands. Some concluded that increasing fines content decrease the liquefaction potential, whereas others observed the opposite. Some of those discrepancies might be explained via various factors such as different confining stresses, different depositional methods, different consolidation histories and possibly different comparison bases (i.e. void ratio, intergranular void ratio, relative density). New experimental results from monotonic undrained triaxial compression tests performed on Nevada Sand-A mixed with different silts indicate that liquefaction behavior is also significantly influenced by the gradation of the fines.

The Effect of Nonplastic Silt Gradation on the Liquefaction Behavior of Sand

San Diego, California
