摘　　要：在试验的基础上,首先描绘出纳米硅水泥土在子午面上的图形,假定偏平面上拉、压屈服点以椭圆线相连,建立了纳米硅水泥土的屈服准则。并与常规岩土材料的屈服准则进行了比较和试验验证,结果表明:建立的屈服函数比较符合纳米硅水泥土的屈服性状。On the base of tests, meridian plane drawings of nanometer silica and cement-stabilized soil are depicted. On the assumptions of elliptic curves connected between tensile points and compressive points, yielding function is deduced, which is compared with routine yielding criterions of geotechnical engineering materials, and verified by tests. The results show that yielding functions in this paper are in agreement with the real properties of nanometer silicon and cement soil.
