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.

摘要： 通过对江垭大坝5向应变计组、无应力计实测数据物理量换算，利用变形法反推应力，得出了江垭大坝混凝土无应力计线膨胀系数、自身体积变形和应变计组实际应力，并对实际应力分布情况进行了分析，得出了江垭大坝重点部位应力应变情况。
