Study on Constitutive Model of Weibull Distribution of Cement-Soil Uniaxial Stress Conditions
According to the results of cement-soil uniaxial compressive test, consider cement-soil stress-strain relations as a continuous random process, the function of random variable obeys Weibull distribution, and introduce generalized hooke′s law in order to establish Weibull distribution of cement-soil constitutive model, solve the softening problem that a variety of incremental nonlinear elastic models cannot reflect the cement-soil. This paper discussed the parameter character of Weibull distribution model of cement-soil, presented the solving method of parameters of cement-soil Weibull distribution constitutive model, verified by results of test, revealed the rationality of the model and shows that the proposed model is more convenient than other model, have widely application value.
