A multi-load miter gate fatigue damage test bed comprises a water tank, a gate body is arranged in the water tank, and the gate body is driven by a hydraulic cylinder to be opened and closed; a pipeline is mounted at the bottom of the water tank, and is connected with the upstream of the water tank through one end of a branch pipe; an electric fan is installed on the outer side of the water tank and right faces the air holes in the water tank. The multi-load miter gate fatigue damage test bench provided by the invention can simulate the operation of the miter gate and the wind load, still water pressure, dynamic water stress and surge action borne by the miter gate during the period. 一种多载荷人字闸门疲劳损伤试验台，包括水箱，水箱内设置有闸门门体，闸门门体通过液压缸驱动启闭；所述水箱底部安装有管道，管道通过支管一端与水箱上游连接、另一端与水箱下游连接；所述水箱外侧安装有电扇，电扇与水箱上的风孔正对。本发明提供的一种多载荷人字闸门疲劳损伤试验台，能够模拟人字闸门的运行以及在此期间受到的风载、静水水压、动水受力以及涌浪作用。
