摘要
根据光电感应理论测量引黄渠道水含沙量,利用过水断面多点布置激光含沙量仪,多点积分法计算过水断面平均含沙量,提出了在线监测渠道断面平均含沙量的新方法,实现了对引水含沙总量和渠道落沙量的监测。通过大量的试验研究和现场测量数据的对比试验,证明此方法操作简便、易实现。
According to the photoelectric induction theory to measure the sand content of the Yellow River Diversion Channel,the laser sediment content meter is arranged at multiple points on the sand section,and the multi-point integration method is used to calculate the average sand content of the water crossing section.An online monitoring method for the average sand content of the channel section is proposed.The new method realizes the monitoring of the total amount of sediment in the water diversion and the amount of sediment falling from the channel.Through a large number of experimental studies and comparative experiments of field measurement data,it is proved that this method is simple and easy to implement.
