为了对某水库非溢流坝结构做安全评价，分别采用材料力学法和有限单元法对该非溢流坝在5种不同工况下的强度和坝体抗滑稳定进行分析，并将采用两种方法得到的结果进行了对比分析；另采用TECPLOT绘图软件对通过使用ANSYS有限单元软件得到的结果进行了后处理，得出了该结构的结果云图。结果表明该非溢流坝除了坝体局部需进行加强外，坝基面应力分布、坝体强度满足规范要求；此外，坝基面的抗滑稳定不满足规范要求，应进行加固处理。
為瞭對某水庫非溢流壩結構做安全評價，分彆採用材料力學法和有限單元法對該非溢流壩在5種不同工況下的彊度和壩體抗滑穩定進行分析，併將採用兩種方法得到的結果進行瞭對比分析；另採用TECPLOT繪圖軟件對通過使用ANSYS有限單元軟件得到的結果進行瞭後處理，得齣瞭該結構的結果雲圖。結果錶明該非溢流壩除瞭壩體跼部需進行加彊外，壩基麵應力分佈、壩體彊度滿足規範要求；此外，壩基麵的抗滑穩定不滿足規範要求，應進行加固處理。

In order to evaluate the safety of non-overflow dam structure of one reservoir,the author applies material mechanics method and finite element method to do a strength and stability analysis of the non-overflow dam under five different loading conditions. Then,the results of two methods are used to do a comparative analysis. Additionally, the result nephograms can be got by using the graphics software TECPLOT,to make a reprocessing analysis of the results that are obtained by the finite element software ANSYS. The results show that the stress distribution of dam foundation surface and the strength of dam body can meet the demands of the relevant specification ,except that some parts of dam body needed to be strengthened. In addition to this,anti-sliding stability of dam foundation surface cannot meet the requirements of the relevant specification and need to be reinforced.
