Abstract

Cyclic stress controlled tests are performed to investigate the degree of liquefaction of sand containing cohesionless and low plasticity fines such as those found in tailing materials. The experimental parameters varied consists of sand void ratio, silt content, and plasticity of silt. The failure is defined as 5% and 10% peak to peak axial strain since the pore pressure does not fully developed and stopps building up when it reaches a value equal to 90-95% of the initial confining stress. 1 Introduction Liquefaction of soils is a complex problem on which a great deal of experimental and numerical research has been done (NRC 8). Much of the research done involved liquefaction of sands. Hence, soils containing some fines are frequently enc
