GUPC – Panama Canal 3rd Expansion, lock gateGUPC – 巴拿马运河三期扩建船闸闸门

The Panama Canal expansion project includes the construction of a third lane of locks alongside the existing lock complexes (the Gatun locks on the Atlantic coast and the Miraflores and Pedro Miguel locks on the Pacific coast, water level difference is 27m). The typical gate structure is 58m long, 35 meter high and 10 meter wide. The design requires very complicated analyses, like dynamic behaviour of the gate under seismic vibration behaviour with oscillated water, high fatigue resistance joints, buckling calculation of stiffened plates both subject to out-of-plane loading and combined analysis with concrete lock head. The project is strictly monitored and controlled by QA system established by canal owner – ACP, which means every single line of calculations is carefully thought through and checked both internally and externally.巴拿马运河扩建项目包括在既有船闸群（大西洋侧 Gatun 船闸、太平洋侧 Miraflores 与 Pedro Miguel 船闸，水位差 27 米）旁新建第三条船闸航道。典型闸门结构长 58 米、高 35 米、宽 10 米。设计需要非常复杂的分析：闸门在地震振动与晃动水体耦合下的动力行为、高疲劳抗力节点、受平面外荷载的加劲板屈曲计算，以及与混凝土闸首的组合分析。项目受运河业主 ACP 建立的 QA 体系严格监控，每一行计算都经过内外部的仔细推敲与校核。
