What is the bulk density of the sandy soil, the uniform load of the ground, the internal friction angle of the soil and the cohesion? Hope master quickly answer. The
Compaction after water stability, high strength, small capillary effect
No cohesion between the particles, the nature of loose, mainly from 0075 to 2 mm of particles composed of plastic-free soil According to the particle size can be divided into coarse sand, sand, fine sand and silt The main mineral composition is quartz, feldspar, mica Sandy soil is exposed to the surface of the various types of rock by physical weathering broken, and then by mechanical handling, abrasion, sorting, accumulation made Pure sand, such as quartz sand, must also be caused by the action of chemical decomposition of unstable minerals Pure sand is an important building material Sandy soil is not adhesive and plastic, but highly permeable Sandy soil is a good aquifer For the construction of the foundation easy to compact, the settlement is small, but in the head and dynamic load, the silt may occur pipe and liquefaction and other adverse engineering geological phenomenon The natural density of sandy soil is the main factor controlling its engineering geological properties According to the degree of density can be divided into loose sand, dense sand and dense sand Sandy soils in Quaternary sediments, as well as modern coastal, river, lake, desert areas with a wide distribution of sandy soil: it has a certain number of coarse-grained groups, so that the roadbed with sufficient strength and water stability, But also to maintain a certain amount of fine particles, so that the soil has a certain viscosity, and will not be too loose The particle composition of the sandy soil is close to the optimum gradation Therefore, the sandy soil construction of the roadbed to adapt to the compaction when driving, can form a solid foundation of the roadbed, rain is not muddy, sunny without dust
Sandy soil [sandysoil] refers to the sand particles are more and have a certain viscosity of the soil
