摘　　要：通过理论研究及实验研究的分析,建立了混凝土复杂受力状态下的强度准则.在此统一准则的基础上,作为特例,分别推导了二轴受力三种状态及常规三轴受力两种状态的强度判别公式.用本强度准则方程式所计算的各类结果都用有关实验数据加以验证.Through the analysis of theoretical study and test results a unified strength criterion of concrete under multiaxia] loading conditions has been established. On the basis of this criterion, not only the triaxial concrete strength can be derectly calculated, but also the formulas for computing the strengths of concrete under three kinds of biaxial loading conditions and two kinds of conventional triaxial loading conditions have been derived. The results calculated by the present criterion equations agree well with the various test data and empirical curves.
