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 hookes 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.
