Liquefaction Behavior of Clean Sand for Various Sample Sizes Using Triaxial Tests
Abstract: A total of 54 isotropically consolidated un-drained triaxial compression tests on various sample sizes were conducted to study the effect of sample size on liquefaction behavior of clean sand. Specimens were prepared using moist placement and dry deposition methods with different initial relative densities and tested for different confining pressures. It was observed that as the sample size increases, deviator stress also increases. Peak value of deviator stress increased as …
