摘要
首次把纳米硅基氧化物作为水泥土的外掺剂,在大量三轴试验的基础上研究了纳米硅水泥土在三维应力空间上及子午面的破坏迹线及其特征,建立了一种5参数水泥土的破坏准则。与实测破坏曲面(线)相比,结果表明该模型基本上反映了水泥土在各种应力下的几何破坏特性。
On the base of abundant triaxial experiments and nanometer SiO2-x powder first stabilized as agent of cement-stabilized soil （NCS）, a general three-dimensional failure criterion for nanometer SiO2-x and cement-stabilized soils （NCS） is proposed; and it includes five parameters. From the result of this comparison, it can be seen that the criterion may be applied throughout the stress range from tensile stresses to high compressive stresses.
