摘　　要：研究发展了一多区瞬态混凝土分解融化模型 ,模型由热影响区、干区、无气体区及混凝土熔渣区构成。应用热平衡积分方法计算混凝土的分解速率和分解深度。研究结果与国外实验结果进行了比较 。The multi region transient concrete decomposition and ablation model is developed. The model consists of a thermally affected region, a dry region, a gas free region and concrete molten slag region. Based on the heat balance integral method, the decomposition velocity and depth of concrete are calculated. The results are compared with the foreign experimental data, and a good agreement is achieved.
