摘要
为模拟二滩高拱坝混凝土的复杂受力状况,利用研制的多功能真三轴加压装置,进行了混凝土试件的双轴、三轴受压,一轴受拉另一轴或另二轴受压下的强度和变形的试验研究。根据试验成果建立了双轴、三轴各应力问关系的回归方程及应力与应变关系式。本项研究为校核二滩高拱坝混凝土的安全度、为高拱坝设计中考虑混凝土的力学特性提供了数据。
To simulate the complicated foree-bearing condition of high arch dam concrete for Ertan Project,the strength and deformation experiment research for biaxial,friaxial compression,tension in one axis with compression in other one or two axes of concrete specimens is conducted by using of prepared multifunctional true friaxial compression apparatus. In the light of test result are established the biaxial and triaxial regression equations of stress correlation and the relations between stress and strain. The research provides information for considering mechanical property of Concrete in high arch dam design.
