水工混凝土结构水力劈裂研究综述
|
摘要
高混凝土坝等水工混凝土结构常年在高水压、高应力条件下运行,易发生水力劈裂破坏,而水工混凝土结构水力劈裂形成和破坏机理复杂。阐述了混凝土损伤断裂模型、裂缝扩展准则的理论研究现状,评述了水力劈裂试验和数值模拟研究进展。指出了当前水力劈裂研究中存在的两个主要难点:数值模型如何考虑缝内水流与结构变形的耦合效应;裂缝扩展准则如何兼顾到渗流作用下微裂缝发生引起的损伤起裂和宏观裂缝扩展引起的断裂失稳判定的问题。最后,提出了高水压作用下的水工混凝土结构水力劈裂有待继续深入研究的工作。
Many hydraulic concrete structures,such as high concrete dams,running perennially in the high pressure and high stress condition,are prone to hydraulic fracturing failure.The forming and evolving mechanism of the hydraulic fracture for concrete structures under high water pressure is extremely complex.Based on the study progress of concrete damage fracture model and crack propagation criterion,the defects in the hydraulic fracturing test and numerical simulation are reviewed.Then,two difficulties in the study of hydraulic fracturing are pointed out.First,how could the conventional hydraulic fracturing numerical model consider the coupling effect between water flow within cracks and deformation of the structure.Second,how could the existing crack propagation criterion used to simultaneously determine the damage crack of micro crack and the fracture stability of macro crack.Finally,some research contents of hydraulic fracturing for concrete structures under high water pressure,which should be in-depth studied,are put forward.
