CREEP DAMAGE CALCULATION MODEL OF QUASI-SOFT SOIL

摘要：

Quasi-soft soil is one of the special soft soils that a suit of carbonaceous soft rocks.It is very important that how to describe the creep damage behavior of quasi-soft soil.For the Bingham creep model,a nonlinear function is introduced into initial creep phase and steady creep phase,and damage is introduced into accelerating creep phase;then,the creep damage constitutive equation is presented on the basis of Xus model.To check the validity of the new model,the creep curves are calculated and compared with experimental data.The results show that the new model has a good consistency with the experimental results.
