基于相关的试验研究成果，提出了一种确定混凝土塑性损伤模型（K＆C模型）强度参数取值的方法。针对K＆C模型损伤参数取值依赖于单元尺寸的问题，以我国混凝土规范为基准，阐述了损伤参数值的调整方法，使得数值计算结果更加合理。利用ANSYS/LSDYNA模拟混凝土常规三轴压缩试验，K＆C模型分别采用本文确定和程序自动生成的强度参数值，并将计算结果与国内外试验结果比较，研究表明：采用本文提出的方法确定K＆C模型强度参数值比较合理。

Based on the related experimental results , a method to determine the strength parameters of the concrete damage model ( K&C model ) was proposed .Because , the damage evolution parameters were mesh -dependent , they were adjusted based on the code for design of concrete structures to make the numerical calcula -tion result more reasonable .In the simulation of concrete conventional triaxial compression test by ANSYS /LS-DYNA, the strength parameters of K&C model were determined separately by the proposed method and automati -cally generating method .By comparing the calculation results with the test results , the study shows that using the proposed method to determine the strength parameters is quite reasonable .
