摘要
经过多次试验和分析,认为圆柱型浮标具有较强的抗风浪能力,可以取代目前洪水测验中使用的十字型浮标。为了统一浮标规格,建议各种型号浮标的通用容重G选用7.84×10~3N/m^3,少沙河流的浮标阻力系数A选用0.023。为了便于应用,给出了含沙量与阻力系数A相应的查算表。
Based on the tests and analysis for many times, the author considers that a cylinder-type buoy for measuring flood is better in against wind and wave than the cross-type one which is applieated widly. In order to seek the unity of buoy standard, it is suggested that the bulk density G of all kinds of buoys should be fix as 7, 84×10~3 N/m^3 and the resistance coefficience A of a buoy used on rivers with lower sediment concentration as 0.023. For the convenience to applicate, the paper gave out the table for selection of the resistance coefficient A according to the sediment concentration of flow.
