WebOct 4, 2024 · Cyclic resistance curves, derived through undrained element tests, are central to the study of liquefaction. Their use implies that water drainage is negligible during an earthquake. Nevertheless, a growing body of evidence suggests that this hypothesis is not realistic. In proximity to the interface of a liquefiable layer with an overlying lower …

This paper aims to study the behaviour of dense RF Hostun sand subjected to dynamic loading in the triaxial cell. The wet tamping method was used to prepare the samples with the same initial conditions including water content and void ratio. The samples were firstly saturated to dissolve the remaining air bubbles inside the samples.
WebFeb 28, 2024 · However, in the present study, the authors have tested Hostun sand mixed with plastic fines, i.e. kaolin and calcigel bentonite clay. The applicability of the equivalent granular void ratio concept to mixtures of sand with clay is a subject of controversial discussion, and there is not much research work on that aspect. WebAug 1, 2011 · In order to investigate coaxiality, or non-coaxiality, between these two principal directions, a series of drained tests on dry Hostun sand was carried out using a precision Hollow Cylinder Apparatus (HCA). The applied stress path includes large Principal Stress Axes Rotation (PSAR). Two of the three principal stresses are kept constant.
