Abstract: The floating trash rack is usually composed of a number of buoys, and forms a chain structure through a wire rope. Therefore, it can be simplified as a flexible structure system. The load analysis is carried out by the simplified assumption of load. On the basis of this, a mathematical model is established, which reflects the load situation more truly, and provides some reference for engineering design.

摘要： 浮筒式拦污栅通常为一定数量的浮筒组成，由钢丝绳串联成一链状，可将其简化为柔性结构体系，并对受力情况进行假定使之简化，在此基础上建立的数学模型能较真实地反映其受力情况，为实际工程设计提供一定参考。
