Abstract
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"build-first,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 Chinese aesthetics and Eastern engineering philosophy.This achievement provides an important reference for the design and construction of similar complex bridge projects and offers a practical example of integrating philosophical thinking into engineering design,promoting technical progress in the bridge engineering field in complex loads and special construction conditions.
In the future,as similar projects continue to advance,it is recommended to further explore how to more widely integrate philosophical thinking and biomimetic principles into bridge design to achieve a dual improvement in structural performance and aesthetic value.Additionally,long-term performance monitoring and maintenance of super-variable heavy load bridges also need to be continuously studied to provide theoretical support and practical guidance for the long-term service of similar projects.关键词
