Liquefaction Susceptibility of Silty Sands Based On Steady State Line Concept
Year: 2019
Type: article
Abstract: Earthquakes are occurring frequently all around the world and causing severe liquefaction-induced damages of civil infrastructures supported on the foundation soil. Hence it is required to analyse the susceptibility of liquefaction in foundation soils including sands, silts, and low plastic clays. Based on the steady state line concept, it is possible to identify whether the soil can be susceptible to liquefaction or not. The steady state line (SSL) can be developed based on consolidated undrained triaxial compression testing data. The susceptibility of static liquefaction can be expressed in terms of the contraction behaviour of soils. The SSL is the boundary line which separates the liquefiable and non-liquefiable soil states. In this study, SSL of silty sand is developed from undrained triaxial test simulations based on the hypoplastic model.
