摘要： 对某坝5向应变计组、无应力计实测应力应变资料进行计算分析，得出了该坝混凝土的温度膨胀系数、自生体积变形、单轴应变，利用变形法反推应变计组的实际应力，并对实际应力分布情况进行了分析，得出了该坝重点监测部位应力应变情况。

Abstract: By analysis on the monitoring data based on 5-d stain meters and stress-free strain meters, linear expansion coefficient, autogenous volume deformation and uniaxial straining were gotten. Afterwards, stress was derived by deformation method. Then, stress distribution and strain of the dam can be analyzed, worthy reference for operation management.
