采用大型有限元分析软件ABAQUS对柏叶口水库泄洪洞出口及渐变段在内水压力作用下的应力、变形进行了数值仿真分析，并评价了其安全性。结果表明，原设计中钢筋混凝土管片，出口及渐变段管壁易出现裂缝，影响了泄洪洞的安全及正常使用。基于计算结果，对出口及渐变段的钢筋混凝土管壁设计进行优化和改进，研究成果对同类工程设计与施工具有指导意义。
採用大型有限元分析軟件ABAQUS對柏葉口水庫洩洪洞齣口及漸變段在內水壓力作用下的應力、變形進行瞭數值倣真分析，併評價瞭其安全性。結果錶明，原設計中鋼觔混凝土管片，齣口及漸變段管壁易齣現裂縫，影響瞭洩洪洞的安全及正常使用。基于計算結果，對齣口及漸變段的鋼觔混凝土管壁設計進行優化和改進，研究成果對同類工程設計與施工具有指導意義。

Adopting the large-scale finite element analysis software ABAQUS,the article carried on the numerical simulation to stress and strain of export and gradual change segments, with internal hydraulic pressure, in the Baiyekou spillway tunnel. And the article evaluated the safety of the spillway tunnel. The results showed that, in the original design of reinforced concrete tube wall, cracks were easy to appear in export and gradual change segments. The safety and normal usage of tube wall were influenced. Based on the results, the design of reinforced concrete tube wall were optimized and improved. All the results afford technical support to construction and design in similar projects.
