Regarding the reinforcement as a engineering anti-seismic measure in the real dam, a numerical model is set up to simulate the reinforcement and the effects on the dam seismic resistance at two water levels are evaluated.

• 讨论并建立了坝体伸缩横缝在地震荷载作用下穿越缝间抗震钢筋的数学模型，给出了动力非线性子结构法考虑缝间抗震钢筋影响的求解公式；并就正常高水位常与低水位两种水位工况，对坝体的抗震性能进行了计算分析。
