硬壳坝有限元分析

Stress Analysis of Hard Shell Dam

硬壳坝由多种材料构成,用传统的计算方法其结果无法准确的反映坝体各部位的应力、变形情况。采用有限元法(ANSYS)计算了某一硬壳坝实例,得出了硬壳坝的坝身应力分布及硬壳与填渣交界面上的应力变形等结果。通过改变填渣弹模进行计算,得出填渣弹模对坝体应力变形的一些影响规律,为设计提供参考,具有较大的实用价值。

Hard shell dam is made up of several kinds of materials. Using traditional calculating ways,it is impossible to obtain precise result of stress distribution and deform of hard shell dam. the finite element software （ANSYS）was used to introduced the computation process of an example,result of stress distribu- tion of dam body and stress and deforw of the surface between the hard shell and the fill were obtained. By changing the elastic modulus of fill, some regular of stress and deform by changing elastic modulus of fill, providing the reference for design can be obtained. It has great practical value.
