摘要
某水库三孔泄洪洞除险加固施工需临时封堵,拟采用双悬臂平面钢闸门整体封堵方案。利用有限元软件ANSYS workbench进行数值模拟,通过有限元法分析双悬臂平面钢闸门结构变形和应力分布情况。研究结果表明,该双悬臂平面钢闸门最大变形分布在闸门面板两侧边缘处,最大值为7.9 mm;最大等效应力分布在闸门主梁腹板中间段外边缘区,最大值为33.2 MPa,满足变形强度要求;安全系数均大于4.9,满足稳定性要求。数值模拟结果与实际工程相吻合,为该类闸门应用提供了依据。
The reinforcement construction of three-holes spillway tunnel in a reservoir requires temporary plugging. Combined with the engineering practice,this project plans to adopt a double cantilever flat steel gate by the integral sealing scheme.ANSYS workbench was used to simulate the deformation and stress distribution of the double cantilever plane steel gate by the finite element method. Research results show that the maximum deformation of the double cantilever plane steel sluice gate is located at the edge of the gate panel and the maximum value is 7. 9 mm. The maximum equivalent stress is distributed in the outer edge of the middle section of the main beam of the gate,and the maximum value is 33.2 MPa,it meets the strength requirements.The safety factor is larger than 4.9,which meets the stability requirements. The numerical simulation results are in agreement with the practical engineering,which provides the basis for application of this kind of gate.
