| 摘 要： | 对经过0、50、100、150、200、250、300 次冻融循环作用后的湿筛大骨料混凝土试件进行了质量损失、单轴抗压试验研究.根据试验结果分析了湿筛大骨料混凝土试件强度降幅随冻融循环次数的变化规律,建立了破坏准则.该准则曲线经验证与实测曲线吻合,为寒冷地区大骨料混凝土结构的强度分析提供了试验和理论依据.

| Abstract: | The experimental researches on weight loss,uniaxial compression strength of wet-screened mass concrete after 0,50,100,150,200,250,300 freeze-thaw cycles are carried out.The failure modes and the direction of surface cracking are observed.The relationship between the decreasing percents of strength and the freeze-thaw cycles is analyzed.On this basis the failure of concrete under uniaxial compression after freeze-thaw cycles is proposed.The experimental and theoretical foundations for strength analysis of ma... |
