The Test Study of Genetic Creep Kernel Function of Artificial Frozen Clay and its Parameters

The test study the creep property of artificial frozen clay at different frozen temperature by independently developed uniaxial creep testing machine WDT-100, the test result indicated that the nonlinear creep property of deep artificial frozen clay can be described by the function as ε=atb. It is found that the creep of deep frozen clay can be calculated by genetic theory through contrastive study, analysis of parameters of genetic creep kernel function shows that the parameter a and creep stress are exponential relationship while linear correlation with test temperature, parameter b is only related to creep stress.
