Descriptions
In this paper, we examine the relationship between pore-water pressure increase and volumetric strain corresponding to it in process of liquefaction of saturated sands, especially influence of membrane penetration. From a series of tests using cyclic triaxial test apparatus, it is found that membrane penetration in sand structure influences to disturb pore-water pressure increase. Therefore liquefaction resistance obtained from cyclic triaxial test apparatus is thought to be overestimated. Then we try to correct the liquefaction resistance by consideration of the effect of membrane penetration and make a comparison with the results obtained from other test apparatus.
