摘要
为了研究液压活动坝的静力特性,针对传统水坝寿命短、安全性差等问题,对结构优化的液压活动坝进行应用分析。通过有限元分析软件,对活动坝进行静力特性分析,根据坝体构件位移和应力值的变化,推测出最优支撑位置,并以此对坝体结构进行静力优化等。结果表明,优化后的活动坝最小应力值为15MPa,最小位移为7mm,最小频率为14.57Hz,表明液压活动坝具有较高安全性,在河道治理领域具有一定的应用价值。
In order to study the static characteristics of hydraulic active dams,an application analysis was conducted on hydraulic active dams with optimized structures.The results show that the optimized movable dam has a minimum stress value of 15MPa,a minimum displacement of 7mm,and a minimum frequency of 14.57Hz,indicating that the hydraulic movable dam has high safety and has certain application value in the field of river management.
