| 摘 要： | 利用大型混凝土静、动三轴试验系统，对经过0、25、50、75次冻融循环的混凝土，进行了5种比例加载路径的双轴压试验，测得了混凝土的强度及两个加载方向的应变，并根据试验结果，系统地探讨了冻融循环后，混凝土在不同比例加载下的双轴受压强度和变形特性。在此基础上，建立了冻融循环后混凝土双轴压的破坏准则，为北方寒冷地区的水坝、混凝土路面等的设计、分析提供了试验及理论依据。

| Abstract: | The strength and strain in two loading direction of concrete after freezing and thawing cycle are experimentally studied using static and dynamic biaxial compression facility. According to the experiment data the behavior of concrete under the action of compression from two direction with various ratios is analyzed. On this basis the failure criterion of concrete under biaxial compression after freezing and thawing cycle is proposed. |

| Keywords: | concrete freezing and thawing cycle biaxial compression failure criterion |
