Abstract: |
Some indoor creep tests for concrete mixed with clay with different ages of the impervious core of the auxiliary dam of Wulapo Reservoir are carried out. According to the experiment results, calculation formulas of the elastic modulus, creep degree and stree relaxation coefficient of the concrete are fitted, and can be used to calculate the measured stress. |
