This paper takes the Shenzhen-Zhongshan Link as the research subject and systematically explores the planning and research approach, investigation and design methods, organizational management model, and innovation pathways for major cross-sea corridor projects, considering its complex construction conditions, functional requirements, and development objectives. As a super cluster project integrating bridges, artificial islands, tunnels, and underwater interchanges, the Shenzhen-Zhongshan Link faces four major technical challenges: "large-scale, soft foundations, extreme heights, and complex interferences". These include enormous traffic demand, construction on extremely soft ground, wind-resistant design for ultra-high bridge decks, and the complexity of multi-node traffic connectivity.
The paper proposes a problem-oriented approach, employing systems thinking and cluster-based strategies to resolve key technical difficulties, while using engineering philosophy to reveal the mechanisms influencing the entire lifecycle of such mega-projects. During the planning and research phase, the study emphasizes the importance of multi-corridor analysis, evaluating route alignments and engineering solutions within the optimal corridor through comprehensive assessment, and ultimately recommending the best implementation plan based on a systems theory framework.
In terms of investigation and design, the Shenzhen-Zhongshan Link adopts standardization, prefabrication, intelligence, and integration as core methodologies. It transcends traditional single-project thinking by establishing a cross-disciplinary, systematic design philosophy and strengthening the synergy between design and construction to leverage the advantages of various specialized resources. The paper provides a detailed analysis of the project's investigation, design organization, and management, highlighting that forming interdisciplinary teams, employing joint design models, and innovating in design-construction integration can effectively tackle technical challenges, shorten schedules, and reduce costs.
Regarding key solutions and comparative analyses, the study discusses overall alignment optimization, landscape design coordination, and innovative approaches at bridge-tunnel transitions. For instance, the Shenzhen-Zhongshan Link adjusted its alignment to meet navigation and aviation height restrictions while using unified styling elements to enhance aesthetic coherence. At the bridge-tunnel junctions, the removal of supports reduced bridge elevation and shortened artificial island lengths, optimizing the overall cluster project.
To address critical technical challenges, the paper advocates a problem-driven research methodology, combining epistemological analysis and experimental methods to drive innovation. Examples include wind tunnel tests to improve the aerodynamic performance of the Shenzhen-Zhongshan Bridge, the 12-hammer synchronous driving technique for rapid island formation in ultra-soft strata, and the groundbreaking use of deep-sea cement mixing piles for immersed tunnel foundations—A first in China. The paper underscores the importance of practical validation, ensuring all innovative solutions undergo simulation tests before real-world application.
Finally, the study summarizes the vital role of engineering philosophy in the Shenzhen-Zhongshan Link, demonstrating how it provides essential methodologies and conceptual tools for complex cross-sea projects. By distilling a universal framework for the planning and construction of cross-sea corridors, the Shenzhen-Zhongshan Link's engineering practice offers theoretical foundations and practical references for future projects of similar scale, while setting a new global benchmark for cross-sea infrastructure development.
