摘要

The soil is generally categorized into sand or clay using different evaluation methods in design practice. However, the medium soils composed of sand and clay are widely distributed in natural systems. The appropriate approach to classify the sand-clay mixture is still insufficient. Natural soils are composed of the grains with various grading curves and different particle characteristics. The unified evaluation method is required to examine the mechanical properties of soil mixtures of sand and fines. Specimens were prepared with natural clay and silica sand with different proportions by weight using the tamping energy method. A series of bending element tests were performed on sand-clay mixture specimens to investigate the influence of fines on the shear modulus.
