运用结构优化设计理论，对６４扇典型弧形闸门门形主框架进行了优化设计，得到了这种门型的主横梁与支臂单位刚度比合理取值范围是２～１２，并对取值影响因素作了分析。
Using the theory of structural optimization design, the optimal design of the door-type main frame of 64 typical arc-shaped gates is obtained. The reasonable value range of the rigidity ratio of the main beam and the arm of the gate type is obtained from 2 to 12, Influencing factors were analyzed.
