利用MicroADV估算泥沙瞬时浓度的试验研究

Experimental Study On The Estimation Of Instantaneous

中文摘要英文摘要

本文利用MicroADV时时均声强和传统量筒称量的时均泥沙浓度的相关关系,建立了之间的数学关系式。进行误差分析后发现:在大流量时估算时均浓度的相对误差在很小的范围以内。把关系式运用到瞬时浓度的估算上,即通过瞬时声强估算瞬时泥沙浓度。结果表明:大流量时,这种估算方法误差在允许范围内。

his paper based the mathematical relation by the correlation between average temporal velocity signal of MicroADV and average sediment concentration . It has proved that the error is within the acceptable limits when the discharge is heavy after analysing the error .Paper take the relation into the estimation of the instantaneous sediment concentration ,it means gets the instantaneous sediment concentration from the instantaneous temporal velocity signal. It has proved that the error is within acceptable limits when the discharge is heavy .
