本文从优化观点出发,探讨船闸闸门的斜杆施加预应力的最优方案,使达到下列要求:1.提高闸门的抗扭刚度;2.抵消闸门因自重而产生的翘曲;3.使自重而产生的竖向位移减少到最小。
In this paper, from the optimization point of view, the optimal scheme of applying prestressing force to the slant gate of shiplock gate is discussed in order to meet the following requirements: 1. To improve the torsional stiffness of the gate; 2: To counteract the warp caused by the deadweight of the gate; 3: The resulting vertical displacement is reduced to a minimum.
