The values of sphericity, roundness and specific surface of sand particles for sand soils of various genesis in Lithuania were studied. For the estimation of the morphometry of sand particles the integral index of morphometry Q was suggested. Parallelly, sand soil strength properties using the direct shear and penetration methods were investigated. One of the factors determining the parametric values of sand soil strength is the morphometric characteristic of sand particles. Morphometric analyses of sand particles of different genesis showed their significant influence on the strength parameters of soils. The morphometric parameters of sand particles of different genesis in different fractions differed significantly. By correlation and regressive analysis the dependence of sand strength parameters on the roundness, sphericity and specific surface of sand particles has been evaluated.
