A Review on Creep of Frozen Soils
Creep of frozen soils is one of the most important topics in engineering activities when frozen soils are involved.This paper firstly gives a review on the previous studies on creep of frozen soils.It is found that extensive experimental work has been carried out,which has facilitated recognition of creep behaviors of frozen soils.As for modeling,due to so many factors such as soil classification,density,water (ice) content as well as especially temperature,focus has been put on empirical models which often precisely describe creep behaviors of frozen soils under certain conditions but with serious limitations for extension.Closed-form models have been a pursuit while they are more theoretical explorations rather than applications so far.Considering this state of the art,a simple method was proposed in modeling the constitutive relations of frozen soil.
