二滩拱坝泄洪表孔闸墩抗震分析

Antiseismic Analysis for Flood Spillway Pier of Ertan Arch Dam

本文采用动力有限元方法,对二滩拱坝表孔闸墩进行了抗震分析。在分析中提出的坝上附属建筑物的抗震计算方法,既有一定的理论基础,又经济简便,有利于实际应用。另外,本文首次计算出高拱坝的加速度分布曲线,对设计具有一定的参考意义。

The dynamic Finite Element Method is used in this paper to carry out antiseismic analysis for Flood Spillway Pier of Ertan arch dam. The antiseismic calculation method for appurtenant structures on dam proposed by the analysis not only has certain theoretical basis, but also is economic, simple and convenient, which is favourable to practical application. Moreover, the acceleration distribution curve of high arch dam calculated for the first time in the paper has certain reference interest for design.
