在保证灌溉水位的基础上，为适当抬高拦河坝的拦截水位，提高灌溉保证率，在拦河坝上往往设置水利自动翻板闸 门，为其克服运行过程中存在的不稳定性，特进行其模型试验，以寻求运行特性。
On the basis of ensuring irrigation water level, in order to properly raise the blocking water level of barrage and improve the guarantee rate of irrigation, water conservancy automatic flap gates are often installed on barrage to overcome the instability existing in the operation process and carry out model tests In search of operational characteristics.
