Creep characteristics considering consolidation degree of dredger fill
摘要
Abstract
Creep characteristics considering the different initial consolidation degrees of dredger fill are studied by using triaxial rheometer TSS10.The results show that consolidation degree has an obvious influence on creep deformation of dredger fill.The creep deformation is more obvious when the consolidation degree is smaller.The increase of consolidation can reduce the creep deformation in a certain degree.The relationship among viscosity coefficient of the creep deformation,consolidation degree and effective consolidation stress substantially is a linearly increasing function.The creep damage strength increases with the increase of the consolidation degree,but is less than the instantaneous strength.The creep stress-strain isochronous curves under different consolidation degrees can be fitted by means of the hyperbolic function.关键词
