地震区闸顶机架最不利受力条件的分析与计算

Analysis and Calculation of Framed Bent on Sluice Pier under Disadvantageous Load Conditions in Earthquake Areas

根据闸顶机架结构特点，按不同的计算模型，分别对机架在顺水流和垂直水流两个主轴方向上进行受力分析，得出最不利的受力情况，并通过实例介绍具体计算方法。

According to the structural characteristics of framed bent on sluice pier and different calculation models,the paper makes load analysis for the framed bent under the load condition of two directions—down the flow and vertical flow to obtain the most unfavourable load conditions.And finally,the paper introduces the calculation method through practical examples.
