摘　　要：引江济淮通航渡槽水桥是一座通水、通航的世界级水桥,也是上下两条河道垂直交叉的水立交。该桥承受着旱、涝水位下近4万t变化的超级可变重载,这在国内外尚属首例,由此带来一系列问题均鲜有先例可循,少知和未知问题突出。渡槽水桥创新创造性提出的左右分幅、一分为二,上桁下拱、合二为一,上开下合、相克相生,外桁内波、对立统一的总体概念设计和工程哲学思想,成功地解决了渡槽水桥特有的上下、左右、内外、表里以及分合、即离、刚柔、虚实的问题。The Yangtze-to-Huaihe Navigable Aqueduct Bridge is a world-class water bridge that integrates both water conveyance and navigation functions,and serves as a vertical interchange for two intersecting waterways.The design of this bridge faces numerous unprecedented technical challenges,including super-variable heavy loads,special construction conditions,lateral stiffness control of wide and flat open sections,and temperature difference effects.To address these challenges,the project team proposed an overall conceptual design and engineering philosophy of"dividing into left and right sections,combining truss above and arch below,opening above and closing below,and integrating external truss with internal waves",which successfully resolved the structural contradictions of the bridge in multiple dimensions and achieved a perfect integration of functionality and aesthetics.The results show that by simplifying complex problems,visualizing conceptual issues with classical theories,and applying biomimetic principles to unknown problems,combined with theoretical calculations,it is possible to avoid complex structures and forces,thereby achieving a"clever"and"ingenious"system.Specifically,the left-right divided design significantly reduces the load on each section,the truss-arch combined structure effectively addresses vertical deflection issues,the corrugated plate application optimizes the load transfer path and achieves a flexible and rigid structure,the W-shaped pit layout and the"buildfirst,excavate-later"construction strategy greatly reduce the construction period and cost,and the stepwise water-filling test verifies the theoretical results and accumulates valuable experience.The design and practice of this bridge not only achieve technical innovation but also reflect the philosophical concept of"following the Dao of nature and simplicity".By integrating everyday phenomena with engineering design and transforming contradictory opposites into a harmonious whole,it successfully interprets the integration of classical Ch
