摘要: 某水电站因机组运行条件变化引起机组剧烈振动,使机组段楼板出现了明显裂缝。基于混凝土损伤力学模型,对楼板裂缝进行了可行而有效的模拟。通过钢筋混凝土结构非线性计算和对比分析,对带裂缝楼板进行各种工况下的结构计算及安全性评价,并结合对比分析结果给出后续结构裂缝处理的指导性意见。

Abstract: Severe vibration takes place in the unit of a hydropower station due to the change of operation condition. And obvious cracks are found in the unit floor. Based on damage mechanics model, a feasible and effective simulation of the cracks is carried out. By means of nonlinear calculation and comparative analysis, structure calculation and safety evaluation of the floor with cracks under various conditions are advanced. Meanwhile, this paper presents some suggestions on crack treatment.
