Abstract

The main object of this investigation is to identify the significance of capillary effects on the dynamic behaviour of partially saturated sand. This is accomplished through an experimental investigation of the factors affecting the shear modulus ratio. The degree of saturation on partially saturated sand shows the influence of the capillarity. The dynamic behaviour of the unsaturated sand is derived from dynamic triaxial tests subjected to sinusoidal loading as far as earthquake-frequencies are concerned. The samples with diameters 10 cm are subjected to different stress states and various degrees of saturation. A further parameter to be varied is the void ratio. 1 Introduction One of the most important soil properties governing the behaviour of sand is the density. Both se
