摘要
通过水工模型试验方法,研究了三峡电站进水口平面快速事故闸门关闭过程中的水力特性及闸门持住力等有关问题。分析了模型试验的相似性问题,然后对影响闸门持住力的几个要素分别进行了分析和验证,从而获得了能降低闸门持住力的几种可行性措施,并给出了确定启闭机容量的有关参数。
Based on hydraulic model test, the hydraulic characteristics of the quick-acting emergency plain gate for the power station of Three Gorge Project during its action and the holding force of the gate are studied herein, in which the comparability the model test is analyzed, and then the main factors effected on the holding force of the gate are analyzed and verified respectively. From the study, some available measures for lowering the holding force of the gate are obtained and the related parameters for determining the capacity of the gate lifter are put forward as well,
