SLOPE FAILURES IN RESIDENCIAL LAND ON FILL DURING GREAT TOHOKU EARTHQUAKE

摘要：

　　As a result of the Great East Japan Earthquake,five slope failures occurred in a residential area on artificial valley fills in Taiyo New Town,Yamamoto,Miyagi Prefecture.The fill material is sandy,derived from the weathering of tuffaceous sandstone which formed the natural ground.Cyclic triaxial tests showed that the fill,which has about Fc =20%,has very low liquefaction resistance,which decreased with application of initial shear stress.Thus,the slope failure in Taiyo New Town can be attributed to the liquefaction of the fill material induced by the intense shaking.
