摘　　要：大渡河猴子岩水电站地处高地震裂度区,同时其进水塔结构较高,需进行结构抗震设计。采用ANSYS有限元软件对猴子岩水电站非常泄洪洞进水塔进行了静、动力分析,研究了进水塔结构自振特性,同时将动力计算结果和静力计算结果叠加,对进水塔的抗震性能进行评价。通过综合比较各工况下的进水塔结构应力计算结果,发现地震、温度荷载是进水塔结构产生拉应力的主要因素,但拉应力范围较小,主要出现在外形突变处,可适当配置钢筋。对进水塔整体结构开展抗滑、抗浮和抗倾整体稳定分析,结果表明进水塔整体稳定性良好。Houziyan Hydropower Station on Dadu River is located in the area of high seismic intensity, so anti-seismic design is necessary for its high intake tower. The static and dynamic analysis are carried out for intake tower of unusual flood discharge tunnel, and its self-vibration characteristics are researched, finally the anti-seismic performance of the intake tower is evalua-ted by superposing the static results and dynamic results. The results show that the tension stress at abrupt surface of the tunnel is in quite a small range, which is mainly induced by earthquake and thermal load, and it can be solved by reinforced concrete. Anti-sliding, anti-floating as well as anti-toppling analyses are conducted to evaluate the integral stability of the intake tow-er, verifying its excellent integral stability.
