| 摘 要： | 利用大连理工大学海岸和近海工程国家重点实验室的大型混凝土静、动三轴试验系统,对常温下普通混凝土进行了5种比例加载路径的双轴压试验,测得了混凝土的强度及应变,并根据试验结果,系统地探讨了混凝土在不同比例加载下的双轴受压强度和变形等力学性能,为处于复杂应力状态下混凝土结构的设计、分析提供理论依据.

| Abstract: | The test of concrete specimens under 5 biaxial proportional compressive stress states were completed using the large static-dynamic triaxial test system for concrete in the State Key Laboratory of Coastal and Offshore Engineering, Dalian University of Technology.The strength of concrete and the curve of stress-strain were measured.According to the experimental results,the mechanical property,such as biaxial compressive strength and deformation under different proportional loadings are analyzed systematically.These conclusions provide theoretical reference for the design and analysis of concrete structures under multiaxial stress states. |
