摘　　要：通过对混凝土破坏的温度损伤机理分析和试验研究,建立了混凝土温度损伤模型,给出了随温度变化的损伤演变方程,分析了混凝土温度荷载下损伤的累积规律,试验结果与理论计算结果规律比较吻合,验证了模型的正确性,并给出了混凝土坝温度损伤的仿真计算方法。Through mechanism analysis and experimental research on thermal damage of concrete,a thermal damage model for concrete and its damage evolutionary equations with varying temperatures are established. The damage accamulating law of concrete under temperature load is analyzed objectively. The theoretical calculation resalts are fairly coincide with the experimental results so as to verify the validity of the model. And a simulating calculation method for thermal damage of concrete is given too.
