Abstract
When we consider a slope stability, it is quite important to know how the modulus of shearing elasticity (which prescribe the intensity and deformation of sand) is distributed at each depth or how it changes in presence of the ground-water level or the moisture of sand. Then (to examine about this problem with high accuracy) we repeated the SHEARING many times and made the ELASTIC CONDITION of sand----the condition under which particle arrangement never changes at its deformation----and proved the next thing by experiments. That is to say, at the same arrangement of particles, the relation between the normal stress and the modulus of shearing elasticity or the shearing strength give the essentially straight lines. We also called the cohesive stress of the capillary water 'Hydro-normal Stress' (which is adhered to the surface of sand particle and perform the same task as the normal stress in the case of shearing) and made an experiment under the conditions of the same arrangement of particles as a clue to elucidate the effect of this stress for the modulus of shearing elasticity or the shearing strength. As the result of this experiments, we proved the next thing. The modulus of shearing elasticity or the shearing strength decrease due to the reduction of the hydro-normal stress which reduce by the change of sand condition (non saturated state to saturated state).
