Investigation of Liquefaction Mechanism in Double Sand Lenses


Ph .D. Candidate, Department of Civil and Environmental Engineering, Amirkabir University of Technology, Tehran, Iran


In many cases of heavy earthquakes, liquefaction has resulted in serious damages. Existing anisotropy in soil layers results  in some difficulties to realize the reason for these phenomena. Loose sand lenses buried in fine soils are one of the cases which may result in these problems and as a weak point during the earthquake can cause this phenomenon. In this paper, using FLAC 2D software, double sand lenses liquefaction mechanism and soil deformation due to applying cyclic loading has been studied and investigated. The FLAC software that has been used for analyzing is capable of modeling progressed models of soil and loading under different conditions.
