Danjiangkou Dam is a control project for the development and protection of the Hanjiang River basin, and is also a water source project for the Middle Route Project of the South-to-North Water Transfer Project. The dam operation safety is the support and guarantee of the national strategy. After the dam heightening, the operating water head will increase, and there may be cavitation, and the downstream scour pit will move upward during the flood discharge process. In order to master the mechanical characteristics of flood discharge after heightening the dam and evaluate the safety of flood discharge structures, the parameters such as bottom flow velocity, dynamic water pressure, flow cavitation noise, and scouring under the dam are mainly observed by means of field hydraulic prototype observation, and the results of previous studies are analyzed. The observation parameters under the design water level are within the safe range. Aiming at the problem that the water tongue of the surface hole impacts the middle wall, the opening order of the flood discharge orifice is optimized. The causes of the scour holes in the flow channel and side wall after the flood season are analyzed and the treatment suggestions are put forward. The problems found and treatment measures can provide reference for similar projects.

丹江口大坝是汉江流域治理开发保护的控制性工程,同时亦是南水北调中线工程的水源工程,大坝运行安全是关乎国家战略的支撑保障。大坝加高后运行水头增加,泄洪过程中可能存在空化空蚀、下游冲坑上移等问题。为了掌握大坝加高后泄洪水力学特性,对加高后泄洪建筑物安全进行评价,通过水力学原型观测的手段重点观测了临底流速、动水压强、水流空化噪声、坝下冲刷等参数,并结合以往研究成果进行了分析。结果表明,设计水位下各观测参数在安全范围内;针对表孔水舌冲击中隔墙问题优化了泄洪孔口开启次序;对流道及边墙汛后出现的冲坑分析了原因并提出处理建议。研究发现的问题及处理措施可为类似工程提供参照。

丹江口大坝是汉江流域治理开发保护的控制性工程,同时亦是南水北调中线工程的水源工程,大坝运行安全是关乎国家战略的支撑保障。大坝加高后运行水头增加,泄洪过程中可能存在空化空蚀、下游冲坑上移等问题。为了掌握大坝加高后泄洪水力学特性,对加高后泄洪建筑物安全进行评价,通过水力学原型观测的手段重点观测了临底流速、动水压强、水流空化噪声、坝下冲刷等参数,并结合以往研究成果进行了分析。结果表明,设计水位下各观测参数在安全范围内;针对表孔水舌冲击中隔墙问题优化了泄洪孔口开启次序;对流道及边墙汛后出现的冲坑分析了原因并提出处理建议。研究发现的问题及处理措施可为类似工程提供参照。

Danjiangkou Dam is a control project for the development and protection of the Hanjiang River basin, and is also a water source project for the Middle Route Project of the South-to-North Water Transfer Project. The dam operation safety is the support and guarantee of the national strategy. After the dam heightening, the operating water head will increase, and there may be cavitation, and the downstream scour pit will move upward during the flood discharge process. In order to master the mechanical characteristics of flood discharge after heightening the dam and evaluate the safety of flood discharge structures, the parameters such as bottom flow velocity, dynamic water pressure, flow cavitation noise, and scouring under the dam are mainly observed by means of field hydraulic prototype observation, and the results of previous studies are analyzed. The observation parameters under the design water level are within the safe range. Aiming at the problem that the water tongue of the surface hole impacts the middle wall, the opening order of the flood discharge orifice is optimized. The causes of the scour holes in the flow channel and side wall after the flood season are analyzed and the treatment suggestions are put forward. The problems found and treatment measures can provide reference for similar projects.
