摘要
对浙江某地软黏土的原状土样、重塑土样以及掺不同含量水泥的水泥土样进行循环三轴试验,比较分析三种土样在动应变、动强度及动孔压比等动力特性方面的异同。结果表明,当水泥掺量达到3%时,水泥土样的动应变和动强度曲线与原状土样非常接近,可以通过掺适量水泥的方法来模拟原状土的动力特性;水泥土样的动强度随水泥掺量呈非线性变化,可采用双曲线函数表达。
The cyclic triaxial tests on natural clay,remolded clay and cemented clay with different content of cement of a kind of soft clay in Zhejiang province were conducted to compare and analyze the characteristics of these three samples in dynamic strain,dynamic strength and dynamic pore pressure ratio. The result shows that the dynamic strain curve and dynamic strength curve of cemented clay with cement content 3% are close to that of natural ones,which indicates that dynamic characteristics of natural soft clay can be simulated by filling cement. The relationship between dynamic strength of cemented clay and the cement content is nonlinear and can be fitted by hyperbolic function.
