摘　　要：为明晰水介质中流冰对平面钢闸门的撞击影响,以某水库的泄洪闸为例,基于流固耦合理论,建立冰-水-闸门三维耦合有限元模型,对平面钢闸门泄水时受浮冰撞击的能量过程进行分析,得出闸门的能量传递规律和应力分布情况。结果显示,在动能驱动下,水与流冰共同作用在闸门上,撞击过程中闸门吸收了大量能量,其所吸收能量最高时占到系统总能量的62.15%,并且距离流冰撞击闸门位置最近的主梁所吸收的能量占到了闸门总能量的58.51%,能量分布集中于撞击区域附近。In order to clarify the impact of flowing ice in water medium on flat steel gate,taking a sluice gate of a reservoir as an example,a three-dimensional coupling finite element model of ice-water-gate was established based on the fluid-solid coupling theory to analyze the energy process of ice impingement during the discharge of flat steel gate,and the stress distribution and energy transfer law of gate were obtained.The results showed that driven by kinetic energy,water and drifting ice acted together on the gate,and the gate absorbed a lot of energy during the collision.The highest absorbed energy accounted for 62.15% of the total energy of the system,absorbed by the main beam of the gate closest to the impact position of the ice accounted for 58.51% of the total energy of the gate,The energy distribution is concentrated near the impact area.
