Abstract
In recent years, ‘Gel-Push’ (GP) sampling has become popular as one of the high quality soil sampling techniques. The GP is able to collect high quality samples by using a lubricant gel that reduces the friction between the tube wall and soil sample. However, an applicability for liquefiable sandy soils has not been examined yet. In this study, the quality of sandy samples collected by GP sampler and conventional triple-tube (TB) sampler were evaluated. The samples were collected in Mihama ward, Chiba City, Japan, where severe liquefaction occurred during the 2011 Off the Pacific Coast of Tohoku Earthquake. Based on the comparisons of void ratio and shear wave velocity between field and laboratory, it was demonstrated that the quality of the GP sample is slightly better than the TB sample. However, there was no significant difference in the value of liquefaction resistance between GP and TB.
