摘要
混凝土断裂力学是20世纪60年代基于金属断裂力学的基本理论基础,而发展起来的固体力学分支。它主要研究含裂缝体的混凝土材料和混凝土结构的破坏过程以及裂缝传播规律,建立断裂准则,探讨如何控制和防止混凝土结构断裂破坏的措施。本文综述了混凝土以及碾压混凝土断裂尺寸效应的现状进行了介绍和讨论。
Mechanics of Conerete Fraeture is a new branch of solid mechanics which arose in1960's.It deals with the damage proeess and the fraetures preading rules of fraetured Conerete materials and struetures,and tries to establish the norms of fraeture and to findout how to prevent concerte struetures from cracking.This paper makes a survey of the emergence and development of mechanics of fracture size effects for concrete and roller compacted concrete and discusses the progress in the field.
