摘要
应用自制的真三轴拉压刚性试验机,结合高拱坝水工混凝土的受力特点,采用立方体试件进行双轴拉压受力试验。根据试验结果,分析了试件的破坏形态、应力应变全曲线和拉压强度,并给出相应的全曲线方程和强度计算公式。
Using the true triaxial compression-tension stiff mechine, self-designed by the au- thor, the biaxial compression and tension of cube concrete specimen with the properties of force-bearing of hydraulic structural concrete of high arch dam has been experimentally stu- died. According to the experiment, failure form, complete tress-strain curves and strength of concrete specimen under biaxial compression and tension are analysed. The corresponding theoretical formulae for calculation are also proposed.
