摘要
系统回顾与阐述了混凝土微观结构与干缩开裂机理,混凝土湿度场、干缩变形宏观计算方法与理论,混凝土湿度场、干缩应力及裂缝模拟的细观力学模型与本构关系研究进展等,指出了混凝土这种复合材料宏、细观湿度特性及干缩开裂机理研究领域仍存在关键瓶颈问题,提出了解决问题的思路与方法,并对未来干缩开裂问题解决所带来的影响进行了展望。
Systematic reviews have been focused on the research advances of concrete micro structure and drying shrinkage cracking mechanism,macro calculation method and theory of concrete moisture field and drying shrinkage deformation,and constitutive relation and mesoscopic mechanics model of concrete moisture field,drying shrinkage stress and cracking.Some bottle-neck problems in macroscopic moisture characteristics and mesoscopic drying shrinkage cracking mechanism of concrete are pointed out,and some ideas and methods for solving these problems are proposed herein.The influences of the solution of drying shrinkage cracking are also previewed.
