Abstract
The 1993 Hokkaido Nansei-Oki Earthquake of magnitude 7.8 caused widespread and significant damage in south west area of Hokkaido, Japan. The soil liquefaction was induced at many locations, which resulted in considerable damage to structures, lifelines, and facilities. In order to evaluate their in-situ liquefaction strengths, the site investigation involved the conduct of standard penetration test (SPT) was performed at several key locations. A series of cyclic undrained triaxial tests was also carried out on soil samples taken from liquefied grounds. Test results showed that the mechanism of increase in the liquefaction strength due to the increase in relative density and the feature of anisotropy in the cyclic deformation behavior of damaged grounds are almost the same with those of clean fine sand such as Toyoura standard sand (Miura et al. 1994). Analysis of liquefaction based on SPT N-value was also performed.
