基于提高动稳定性的拱坝拱圈结构抗震优化设计

Anti-seismic optimization of arch rings for raising dynamic stability of arch dam

摘要: 提出了表征结构抗震动稳定性的能量函数，推导了能量函数的表达式，并以拱坝的拱圈为算例，进行了优化设计，结果表明，降低了拱圈结构的地震反应能量，提高了抗震能力。

Abstract: An energy function and an expression reflecting structural anti seismic dynamic stability are developed. Optimization results of arch rings show that the reaction energy is lowered and the anti seismic capacity raised.
