水文缆索法测流悬索偏角(10°<θ<45°)与水深d的分析及推求

Analysis and Calculation of Hydrological Cable Method to Gage Flow Cable Angle(10°<θ<45°) and Water Depth

我国江、河等水文站常用的桥测、缆道、船测等测流方法均采用铅鱼、悬索流速仪法测速、测深。用不同测深方式对影响水深的各项因素作较全面考证和深入分析。运用代表站实验悬索偏角资料,经率定、分析、概化、归纳,推导出可用于已知某垂线水深、流速和测深铅鱼重量与悬索几何尺寸等数据建立求解悬索偏角(10°<θ<45°)的模型化适用公式。

Bridge,cableway and ship surveying method used commonly in the hydrological station for Chinese rivers all adopt fish lead and cable current meter to survey the velocity and depth. Each factor affecting water depth was researched overall and analyzed further in different sounding ways. Applying tested cable angle data of representative station to calculate the known vertical water depth ,flow velocity and weight of sounding fish lead and cable physical dimension through calibration, analysis, generalization and conclusion used to establish the formula to find the cable angle （10°〈θ〈45°） suitable for modeling
