In order to research the effect of partic1e size on shear strength and coefficient of earth pressure at rest of sands, the triaxial compression tests and the experiments of earth pressure at rest were carried. After analysing the results obtained by experiments, the following conclusions were obtained. (1) Internal friction angle, φ' , of sands increases with a decrease of partic1e size. (2) Difference of shear strength of sands based on particle size is due to the volume change behaviour at failure. (3) Coefficient of earth pressure at rest, K。, of sands increases with an increase of particle size. (4) Existence of fine particle in sand causes a decrease of K。-value.
