A Simple One-Scale Constitutive Model for Static Liquefaction of Sand-Silt Mixtures
Instability of liquefaction is one of the major reasons which results in the failure of earth structure such as dam. The present study focuses on the simulation of static liquefaction behavior for granular materials such as sand and sand-silt mixtures. Based on micromechanical analysis of inter-particle behavior, a simple one-scale model is proposed to simulate the stress-strain response of san...
متن کاملInvestigation of Liquefaction Mechanism and Displacement in Buried Sand Layers
One of the most important reasons for damages during earthquakes is the liquefaction of loose and saturated sand soils. However, in many regions with proper soil specifications, the large settlements have been observed in the ground surface. Loose sand layers buried in fine soils are one of the cases which may result in these problems and as a weak point during earthquake can cause this phenome...
متن کاملInvestigation of Liquefaction Mechanism in Double Sand Lenses
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, doub...
متن کاملliquefaction resistance of sand-silt mixtures using laboratory based shear wave velocity
laboratory data, which relate the liquefaction resistance of firoozkooh sand and non-plastic silt mixtures to shear wave velocity are presented and compared to liquefaction criteria derived from seismic field measurements by andrus and stokoe [1]. in the work described herein, cyclic triaxial and resonant column tests were conducted on specimens of clean sand and sand-silt mixtures with silt co...
متن کاملThe effect of nano-Kaolinite on liquefaction resistance of liquefiable sand
This study is an attempt to investigate the effect of the nano-kaolinite concentration on the liquefaction resistance of liquefiable sand from Gorgan city of Iran. To examine the influence of the nano-kaolinite concentration on the liquefaction resistance of nano-kaolinite-sand mixtures, three different nano-kaolinite concentrations: 3%, 6% and 9% were prepared. Cyclic triaxial tests were condu...
