摘要
铁堰是一座以灌溉引水为主,兼顾防洪的水利枢纽工程,为主副堰布局堰坝。对其结构稳定分析表明,副堰的设置提高了堰坝整体稳定性;使用Flow-3D软件分别模拟铁堰在只有主堰时和主副堰共同作用时不同水位的过流能力。研究表明:在堰顶水深恒定的情况下,副堰基本不影响整体的过流能力,随着水位的上升,在同一水位主堰的过流能力大于主副堰。分析得到铁堰拦河堰坝在经过加固处理后其应力状态和稳定性均达到使用标准,拦河堰坝的过流能力基本不受主堰和副堰的影响。
Tieyan Sluice is a water conservancy project with the layout of the main and the auxiliary weirs which focuses on irrigation and water diversion as well as flood control.The structural stability analysis shows that the setting of the auxiliary weir improves the overall stability of the weir.The Flow 3D software is used to simulate the flow capacity of Tieyan Sluice at different water levels when only the main weir or the main and the auxiliary weirs work together.The research shows that in the case of constant water depth at the top of the weir,the auxiliary weir basically does not affect the overall flow capacity.As the water level rises,the flow capacity of the main weir is greater than that of the main and the auxiliary weirs at the same water level.The analysis shows that the stress state and stability of Tiayan Sluice after reinforcement treatment have met the standards and the flow capacity is basically not affected by the main and the auxiliary weirs.
