左江水利枢纽安装间坝段结构计算

Structural calculation for the dam section with erecting bay in the Zuojiang water resources pivotal project

利用三维有限元法分析计算了左江水利枢纽安装间坝段的应力。计算表明用材料力学法计算结果误差太大，用板梁体系计算过于复杂，用三维有限元法成果可以大量节省钢筋。

With three dimensional finite element method, the author analysed and calculated the stress of the dam section with erecting bay in the Zuojiang water resources pivotal project. The calculation result indicated that result's error is too big, and computing that by the material mechanical method for girder system is too complex. But using 3-dimensional finite element method's result may save on quantities of reinforcing bars, and some section's stress is opposite to the former.
