浮式拦污排设计参数分析

将采用钢丝绳张拉的电站进水口浮式拦污排假设为理想的悬索（平面柔性结构），把水流、风和波浪等对浮式拦污排的作用简化为作用在悬索的荷载，建立数学模型，对其设计参数进行分析。结果认为导出公式的计算精度能满足工程设计需要，表达形式适合工程设计使用。

Design parameters analysis of floating trash barrier

The floating trash barrier designed for the intake of hydropower station was assumed to be an ideal cate-nary system（planar flexible system）by use of steel wire tension,and the action of water flow,wind and wave onto the barrier were simplified as loads on the catenary system,based on which the mathematical model was set up and the design parameters were analyzed. It was concluded that the calculation results out of the derived formula can sat-isfy the accuracy requirements and the formula form is applicable for engineering design.
