Laboratory investigation into the undrained monotonic behaviour of saturated Algeria sand
This paper presents a laboratory study on the monotonic behaviour of saturated chlef sand (Algeria). Through its history, many different phenomena have been observed in this soil (Chlef sand, Al-Asnam earthquake 10 October). For this laboratory study, a series of tests were performed on sand samples from Chlef to see how the initial relative density and lateral pressure (confining) affected how the sand behaved. The tests results indicated that the increase in the relative density and the confining stress significantly affects the undrained monotonic behaviourof the sand under study resulting in an amplification of the dilatant character with the increase in the relative density, on the other hand a decrease in the dilatant character with the increase in the initial confinement pressure. The results also indicate a strong correlation between the shear strength measured by the stress deviator and the effective mean pressure P’.
