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。
大渡河猴子巖水電站地處高地震裂度區,同時其進水塔結構較高,需進行結構抗震設計。採用ANSYS有限元軟件對猴子巖水電站非常洩洪洞進水塔進行瞭靜、動力分析,研究瞭進水塔結構自振特性,同時將動力計算結果和靜力計算結果疊加,對進水塔的抗震性能進行評價。通過綜閤比較各工況下的進水塔結構應力計算結果,髮現地震、溫度荷載是進水塔結構產生拉應力的主要因素,但拉應力範圍較小,主要齣現在外形突變處,可適噹配置鋼觔。對進水塔整體結構開展抗滑、抗浮和抗傾整體穩定分析,結果錶明進水塔整體穩定性良好。

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.
