根据水泥土单轴抗压试验结果,将水泥土应力～应变关系视为连续随机的过程,且随机变量的函数服从于Weibull分布,并引入广义虎克定律建立了水泥土Weibull分布本构模型,解决了各种增量非线性弹性模型不能反映水泥土软化问题。本文讨论了水泥土Weibull分布模型参数特征,同时给出了水泥土Weibull分布本构模型参数的求解方法,并与试验结果进行验证,揭示了该模型的合理性,表明该模型较其他模型简便,具有广泛应用价值。
According to the uniaxial compressive test results of cemented soil, the stress-strain relation of cemented soil is regarded as continuous random process, and the function of random variable obeys Weibull distribution. The generalized Hooke’s law is introduced to establish the Weibull distribution constitutive model of cemented soil, Solve a variety of incremental nonlinear elastic model can not reflect the problem of cement soil softening. In this paper, we discuss the parameter characteristics of Weibull distribution model of cement soil and give the method to solve the constitutive model parameters of Weibull distribution of cement soil. The method is validated with the test results. The rationality of this model is revealed, which shows that the model is simpler, Has a wide range of applications.
