临溪水文站缆道流速仪法流量简测分析研究

临溪水文站流量测验主要以缆道流速仪法为主,常规测验方式虽能保证流量精度,但测验时间较长,无法满足时效性的要求。因此,本文通过对临溪站多年的缆道流速仪法流量进行测速垂线分析,在常测法基础上提出了流量简测方案,并对前后流量进行了误差分析,测验结果满足规范要求。研究结果可为类似水文站测验提供参考。

Analysis and research on simple flow measurement of cableway current meter method in Linxi Steam Water Station

The flow test of Linxi Steam Water Station is mainly based on the cableway anemometer method.Although the conventional test method can ensure the flow accuracy,the test time is too long to meet the timeliness requirements.Therefore,in this paper,based on the vertical analysis of the cableway current meter method flow in Linxi Steam Water Station for many years,a simple flow measurement scheme is put forward on the basis of the constant measurement method,and the error analysis of the flow before and after is carried out,and the test results meet the specification requirements.It can provide reference for similar hydrological station test.
