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。
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 actu- al stresses on the strain meters were gotten. Further, stress distribution and strain of Jiangya dam can be analysed, worthy reference for operation management.
