| Abstract: | By conversion of physical quantities in the monitoring data by 5-d stain meters and stress-free strain meters, stress was derived by deformation method, as well, linear expansion coefficient, autogenous volume deformation and actual stresses on the strain meters were gotten. Further, stress distribution and strain of Jiangya dam can be analysed, worthy reference for operation management. |

| Keywords: | linear expansion coefficient autogenous volume deformation uniaxial strain deformation method uniaxial stress dam |
