中文摘要:
      为有效解决万家埠水文站长期存在的悬移质测验难题,对该站原有测验方式进行了优化。文章介绍了AYX2-1型悬移质采样器的工作原理及其在万家埠水文站的比测试验情况,通过对2019年以来高、中、低水位级试验数据的对比分析,采样器进口流速系数和采集样品的一致性符合规范要求;依据采样器的工作原理和万家埠水文站的悬移质日常测验方案,分别针对单、断沙以及特殊水情期间的采样构建了相应取样模型,提升了取样效率和精度,可操作性强。
英文摘要:
      In order to effectively solve the long-standing problem of suspended load test at Wanjiabu hydrological station,the original test method of the station is optimized.The article introduces the working principle of the AYX2-1 type suspended mass sampler and its comparative test results at the station.The comparative analysis of the test data,collected from the high,medium and low water levels since 2019,shows that the sampler inlet flow rate coefficient and the consistency of the collected samples can meet the requirements of the specification.According to the sampler,the working principle and the daily test plan of the suspended load of the station,the corresponding sampling models were constructed for the sampling during the single,sand-breaking and special water regimes,which improve the sampling efficiency and accuracy,and the operability is strong.
