摘要
利用考虑钢筋滑移的拱坝横缝配筋动力非线性模型 ,对设计地震荷载工况下的小湾拱坝进行了三维动力非线性有限元分析 ,研究了跨缝钢筋与周围混凝土的粘结质量、钢筋直径等因素对跨缝钢筋控制横缝变形的影响 。
With the help of a new numerical model for reinforced joint considering the bond and slip between reinforcements and surrounding dam concrete, authors conducted 3D FEM nonlinear analysis for Xiaowan arch dam under design load in case of earthquake, and analyzed the effects of different bond quality between reinforcements and dam concrete, different diameter of reinforcements on controlling the transverse joint opening. The results provide helpful sggestion for the application of the joint opening controlling measure.
