[摘要]  为了统一ABAQUS混凝土损伤塑性模型与规范提供的混凝土本构模型，在规范提供的混凝土本构关系的基础上引入损伤因子的概念，对混凝土损伤塑性模型本构关系参数的确定方法进行了研究。用各等级混凝土本构关系参数模拟结果与规范曲线的对比，验证CDP模型参数的正确性：用一混凝土剪力墙试验的模拟分析，验证本构关系参数用于结构分析情况下的可靠性。两种验证结果证明，给出的CDP模型参数确定方法是正确的，用该方法确定的参数进行结构模拟分析所得结果是可靠的，并指出了CDP模型的不足。

Abstract: To uniform the concrete damaged plastic model provided by ABAQUS and the concrete constitutive relatiouships provided by the code for concrete structure design, the damaged factors was introduced into the constitutive relationship provided by criterion, and then the method used to determine the parameters of CDP model was studied. To verify the correctness of the parameters of CDP model, the method of contrasting the results extracted from simulation and the criterion curves is used; and to verify the reliability applied to structure simulation, the method of contrasting simulation results and experimental results is chosen. It is approved that the determined method of CDP model parameters is correct and the simulation results of structures using the paramleters determined by the ruethod is reliable.The shortage of CDP model was indicated.
