| Abstract: | The mechanical properties and features of two main components of the Three Gorges Project's Phase II cofferdam are obtained based on sampling and experiments and the deformation law is found.Based on the experimental results and measurement,the 3 parameters rheological model is put forward,which can describe not only the behavior of creep,but also the feature of stress relaxation and that corresponding with the viscoelasticity of majority materials for the cofferdam material.The model meets the viscoelastic... |
