摘要
"缓蓄快放"是一种模拟溃坝以增大流速冲淤的技术,针对目前"缓蓄快放"冲淤效果理论计算不成熟、试验测量不准确的特点,研发了一种新型的水流冲刷力测量装置,并进行了室内模型试验。试验结果显示,该装置具有结构简单、设计科学、测试快速、数据可靠、结构稳定性强的特点,为极端流态溃坝过程中水流冲刷力测量提供了新的工具。
The‘slow storing and quick draining'theory was proposed on the basis of simulation of dam break to increase the water flow. Since the theoretical calculation of flushing effect was immature and the experimental measurement was inaccurate of the current ‘slow storing and quick draining'theory,this study developed a new device for water erosion force measurement and conducted a door model test. The test results show that the device has advantages of simple structure,scientific design,reliable data,strong structural stability,and can be tested fast. Therefore,it provides a new tool for water erosion force measurement in the dam-break process of extreme flow pattern.
