摘要:
提出了含裂缝拱坝的动力分析方法,采用弥散裂缝模型模拟混凝土的开裂行为。将该方法应用于某300.0 m级高拱坝带缝工作时的局部损伤研究,考虑了裂缝位置对局部损伤程度的影响。结果表明,拱向裂缝在遭遇地震时会产生不同程度的局部损伤。裂缝位于坝体中部高程时的局部损伤程度比位于坝体底部高程时严重;拱向裂缝距离坝体下游面越近,局部损伤越严重。拱向裂缝附近的局部损伤可能贯通甚至扩展到邻近坝段,因此,对坝体中的裂缝应及时加以处理。
Abstract:
The dynamic analysis method for arch dam with crack was proposed in this paper, in which smear crack model was employed to simulating cracking behaviors of concrete. Based on this method, the local damage of a 300.0 meters level high arch dam working with crack was studied, considering the influence of crack position to local damage degree. The results show that various degrees of local damage will be produced nearby the crack when arch dam undertakes earthquake. The local damage degree of crack located in dam middle height is more serious than the one in dam lower height. The closer the crack nearby the downstream, the more serious the local damage is. The local damage nearby the crack may coalesce and even spread to neighbour dam section, so timely treatment to these cracks is necessary.
