摘　　要：某水电站冲沙孔在施工期即发生破裂坍塌事故,采用ANSYS建立冲沙孔段的三维有限元模型,对冲沙孔结构进行复核计算分析。通过应力图计算结构配筋,与实际配筋对比,分析冲沙孔破裂的原因。The sand flushing sluice of a hydropower station ruptured and collapsed during construction.ANSYS is used to establish a three-dimensional finite element model of the sand flushing sluice section,and the check calculation and analysis of the sand flushing sluice structure are carried out.The reinforcement of the structure is calculated based on the stress diagram,and compared with the actual reinforcement to analyze the cause of the rupture of the flushing sluice.

关 键 词：冲沙孔 破裂坍塌 结构配筋 复核计算
