The Bivariate Model of Double-line Method-based Moistening Deformation Coefficient

Xi Chen, Hong Guo


The paper analyzes the express method of double-line method-based moistening deformation coefficient, which can be expressed as the strain difference with same pressure and different water contents. Through the analysis it is found that the key point of constructing moistening deformation coefficient bivariate model is to obtain the function relation of strain, stress and water content. And then, the paper discusses the concept of constructing moistening deformation coefficient bivariate model under confining compression test conditions. In combination with the specific test shows the bivariate model of moistening deformation coefficient realizing process. Finally, the verification test results show that the model is reasonable.
