人字闸门斜杆预应力优化研究

Research on Optimization of the Diagonal Brace Prestress of a Miter Gate

应用平面壳体单元的有限元法计算人字闸门位移及应力．应用线性规划优化方法得出一组较小的预应力值，另外，还使用“预拉力和极小”的目标函数，得出同样成果．

This paper calculates displacements adds stresses, of a miter gate, using the finite alement method of the planar shell element. Using optimizing method of linear planning, a group of smaller prestress values are obtained. In addition, usins the minimal object function of the pretension summation, the same solution is obtained.
