摘要：The strain softening characteristics of the roller-compacted concrete (RCC) level is a key condition in studying the bearing capacity of RCC dam. Assuming that the RCC dam unit is in the adiabatic condition, horizontal and vertical linear expansion coefficients of the RCC level are calculated. These methods were applied in practical engineering, and equivalent thermodynamic parameters can be obtained by taking the weighted squared residuals between numerical values and monitoring data as the optimization objective function in parameter inverse analysis. And the difference of the Poisson ratio and the elastic modulus, the hampering of the ontology on the layer could be reflected accurately.
