Aiming at the shortcomings that traditional water weirs cannot measure the sand content of runoff and the traditional measurement methods are not accurate, it is difficult to realize online measurement in the field of dam water weirs. By analyzing the negative correlation between the sand content of the water flow of the water weir and the gray value of the image, sand volume measurement technology was proposed to automatically measure the sand content of the water flow of the weir. The test results show that the deviation between the detection result of sand content and the actual value is low, and it is a convenient, efficient and real-time determination method. The research results have certain reference value for dam seepage monitoring.

针对传统量水堰无法测量径流含砂量且传统的测量方法精度不高,难以在大坝的量水堰现场实现在线测量的不足,提出了一种基于量水堰的大坝渗流含砂量测量技术,通过分析量水堰水流含砂量与图像灰度值之间的负相关性关系,自动测量量水堰水流含砂量。试验结果表明,含砂量的检测结果与实际值偏差较低,是一种具有一定的便捷性、高效性、实时性的测定方法。研究结果对坝体渗流监测具有参考价值。

针对传统量水堰无法测量径流含砂量且传统的测量方法精度不高,难以在大坝的量水堰现场实现在线测量的不足,提出了一种基于量水堰的大坝渗流含砂量测量技术,通过分析量水堰水流含砂量与图像灰度值之间的负相关性关系,自动测量量水堰水流含砂量。试验结果表明,含砂量的检测结果与实际值偏差较低,是一种具有一定的便捷性、高效性、实时性的测定方法。研究结果对坝体渗流监测具有参考价值。

Aiming at the shortcomings that traditional water weirs cannot measure the sand content of runoff and the traditional measurement methods are not accurate, it is difficult to realize online measurement in the field of dam water weirs. By analyzing the negative correlation between the sand content of the water flow of the water weir and the gray value of the image, sand volume measurement technology was proposed to automatically measure the sand content of the water flow of the weir. The test results show that the deviation between the detection result of sand content and the actual value is low, and it is a convenient, efficient and real-time determination method. The research results have certain reference value for dam seepage monitoring.
