摘要：

Proper nanometer silicon SiO2-x can increase the compressive strength of cement-stabilized soils and improve the engineering properties. On the basis of abundant experiments, the influence factors of compressive strength of nanometer silicon and cement stabilized soils (NCS) and their magnitude are analyzed by using the orthogonal tests, and the optimum proportion of NCS is given. Based on the regressive theory, a linear regression model of compressive strength of NCS is presented and is verified. The tests show that the nanometer silicon power can increase the compressive strength dramatically. The main influence factors of NCS are percentage of cement, nanometer, confining pressure and water cement ratio. The above influence factors can be arranged as follows: cement percentage → confining pressure → nanometer percentage → water cement ratio. The cement addition has significant effect on the strength of NCS, while the confining pressure and the percentage of nanometer silicon have dramatical effect on the strength, and the water cement ratio has certain influence on the strength. Relevant equations are set up by using the linear regression theory to predict the strength of NCS. Conclusions from the tests and analyses are significant for further studies on properties and curing mechanics of NCS.
