中美两国水电站拦污栅设计标准的比较

Comparison of the Design Standards of Trash Racks for Hydropower Stations in China and the United States

介绍了中美水工钢结构设计规范中对电站拦污栅的设计准则及要求,对各规范的条文内容进行了解读、比较,并以国外某水电站引水发电系统进口拦污栅施工图的设计为例,从荷载工况、结构设计、水头损失、栅条振动等方面对美国设计规范的相应条款及规定进行说明,以加深对该规范内容的理解。

The article first introduced the design criteria and requirements of trash racks for hydropower stations in the Chinese and American hydraulic steel structures design specifications and interpreted and compared the contents of the various specifications.Secondly,taking the design of the construction drawing of the imported trash rack of a foreign hydroelectric power station as an example,the corresponding provisions and regulations of the U.S.design code are explained in terms of load conditions,structural design,head loss and grid vibration to deepen the understanding of the content of this specification.
