1998年汛期隔河岩水利枢纽观测部位为深孔、表孔及消能工。其观测内容包括流态、时均压力、空化噪声、流速、雾雨。观测结果表明 :该工程泄洪表孔、深孔、消力池及辅助消能工的各项水力学特性基本良好。泄水建筑物过流面、一级池两边岸坡均无蚀损 ,二级消能工上的消力墩、差动坎等均基本完好无损 ,但 1 998年 2月抽干检查发现消力池有局部磨损 ,左岸隔流堤护岸在 1 998年泄洪过程中发生局部坍滑。由于集中坝身泄洪 ,泄洪时雾化现象较严重 ,故须采取措施 ,以确保工程安全运行。将部分原型观测资料与模型试验资料和计算值作了对比 ,总趋势和数值基本一致
The observation points of Geheyan Water Control Project in flood season in 1998 are deep holes, surface holes and energy dissipators. The observations include flow regime, hourly average pressure, cavitation noise, flow rate, foggy rain. The observation results show that the hydraulic characteristics of the spillway, deep hole, stilling pool and auxiliary energy dissipater of the project are basically good. There was no erosion on the flow surface of the drainage structures and the bank slope on both sides of the primary pool. The dissipation pier and differential ridge on the secondary energy dissipater were basically intact. However, in February 1998, The local pool has partial wear and tear, and partial bank slip occurs during flood discharge in the left bank of the river bank in 1998. Due to the concentrated flood discharge in dam body and atomization phenomenon during discharge, it is necessary to take measures to ensure the safe operation of the project. Some prototype observation data and model test data and calculated values are compared, the overall trend and the value of the same
