Based on the Ginzburg-Landau phase transitions theory and within the framework of continuum mechanics and phenomenological theory,a new method which uses analog phase-change idea of synergy theory is proposed to the study of the phase transitions of concrete damage.This paper employs Ginzburg-Landau phase transition theory to the research of phase transition of concrete damage and achieves a good result.Firstly it deduces the model which describes phase change of concrete damage,and then analyzes the linear and nonlinear solutions of damage model and relative functions.Finally,a large numerical simulation software named RFPA is used to verify the correctness of the theory.%基于Ginzburg-Landau相变理论,在连续介质力学与唯象理论的框架内,利用协同学系统相变类比的思想,提出了一种新的研究混凝土损伤相变的思路,即将超导相变的Ginzburg-Landau理论类比到混凝土损伤相变过程中来,并且取得了良好的研究成果.首先推导出了混凝土损伤相变的本构模型表达式,并计算出了损伤模型的线性解和非线性解及其相关函数,然后用大型数值模拟软件RFPA进行模拟验算,验证了该研究成果的正确性.
