| 摘 要： | 以宝殊寺水利工程为研究对象，研究采用有限元法对其复杂地基整体应力进行了分析．结果表明，与材料力学计算比较，在离地基1／3坝高以上，应力分布与材料力学计算结果较为接近，而靠近地基和基础部分应力变化较大。因此，应力分析的有限元法比材料力学方法计算更真实地反映出基础应力分布的情况。为选址和设计提供了重要的科学依据.

| Abstract: | The finite element method(FEM) was used to analyze the full stress of the complex ground base in the Baozhusi Water Conservation Project.Compared with the calculation methods in material mechanics,FEM gave similar results of stress distribution in the part of 1/3 dam height from the ground base.However,the results of calculation of stress distribution in the part close to the ground base and foundation.FEM can reflect stress distribution more accurately than the conventional calculation methods in material mechanics and is, therefore,recommended for adoption in dam site choice and design. |
