Abstract


Along with the rapid development of science and technology, the water in the soil engineering application more and more widely. Cement soil in the strengthening effect is the first, can significantly improve the mechanical properties of the soil. In recent years, as construction materials science of rapid development, and human in the water for earth to play a greater role in the new material. Because of China’s development status of extreme uneven, new material in the regional application also have bigger difference. This article from that starting point, in view of the Inner Mongolia sand and a lot of cheap wind-blown sand resources research, in water with a certain amount of sand soil deposited sand and wind, through the indoor no lateral restraint compressive strength test, triaxial compression test and SEM scanning the test, the sand and wind deposited sand material of soil-cement mechanical performance improvement effect and strengthening mechanism. According to the research results are as follows:1, Whether for wind-blown sand or sand distinct improvement of the mechanical properties of the soil, improve the strength of the soil, make the deformation characteristics and to the direction of the engineering practice to development. And give the sand and wind deposited sand mixed quantity and strength of the relationship, for future research and engineering practical reference.2, The soil sample to the triaxial compression test, the shear strength of the change was also studied, and concludes that the soil water with wind-blown sand, and the friction Angle of little influence the shear strength enhanced mainly comes from the increase of force stick together. And through the test of the stress-strain curve get any research on the constitutive relationship.3, Further through the wind-blown sand of various components of the particle grading test and SEM using scanning electron microscopy (SEM) analysis of soil water of components of composite soil strength of the influence and function mechanism of each other, more explicit cement, earth, wind deposited sand through a series of physical and chemical reaction, the soil strength increased contributions.4, Through the sand and wind deposited sand effect on the strength of cement-soil, analysis of two the additive agent on the contribution of the difference between soil.
