摘要
对混凝土本构关系的发展、沿革、应用及存在的问题进行梳理和评述,概括分析各类本构关系具有代表性的研究成果。研究指出混凝土本构关系研究在试验技术、理论研究、学科交叉等方面存在的关键科学问题;从学科融合、监测检测技术手段发展等方面对本构关系的发展指出了研究方向;阐明损伤力学本构与人工智能神经网络技术本构具有广阔发展前景;指出特殊环境下专门性本构模型有待进一步深入研究。
The study reviews the development, evolution, application and existing problems of concrete constitutive relation, summarizes and analyses representative research achievements of various constitutive relation. The study points out key scientific problems of concrete constitutive relation in testing technique, theoretical research and cross-disciplines; it indicates the development direction of constitutive relation from the aspects of discipline integration, the technological means of monitoring and inspection and others; it illuminates that constitutive damage mechanics and constitutive artificial intelligence neural network technique enjoy a broad development prospect; it also states that a further research is needed in technical constitutive model tinder special circumstance.
