Residual undrained shear strength, su, of granular soils is often estimated from back analysis of post-earthquake geometry of embankments. In these analyses soil behavior is usually assumed to be inherently isotropic although saturated sandy soils exhibit strong inherent anisotropy under undrained loading. This paper presents back-analyses of two case histories of undrained instability of embankments observed during the Magnitude (Japanese Meteorological Agency) 7.8 (MJMA 7.8) Kushiro-Oki Earthquake of January 15, 1993 considering inherently anisotropic soil behavior. The residual undrained shear strengths obtained from these analyses were then compared with the corresponding estimates from conventional back-analyses which assume inherently isotropic soil behavior.
