Application of 3D Virtual Digital Visualization Technology in the Simulation and Modeling of Cross-Sea Network Engineering

Introduction

Cross-sea network engineering, through the construction of cross-sea bridges and submarine cables, can effectively overcome geographical boundaries and strengthen transportation and power network connections between regions (Liu et al., 2023). This not only promotes the optimal allocation of resources but also drives industrial development and economic prosperity in the regions along the route. Cross-sea bridges are a crucial component of cross-sea network engineering (Zhang, 2021). The construction of these bridges not only overcomes challenges, such as harsh natural environments and high construction difficulty, but also shortens construction time and improves project quality through technological and management innovations. Submarine cable power transmission is another key component of cross-sea network engineering (Wang et al., 2021). It transmits electricity from the mainland to islands or across straits through submarine cables, achieving long-distance power transmission and supply. Submarine cable power transmission projects are characterized by high costs and complex construction and maintenance, which impose high demands on safety and reliability (Chen et al., 2023). Cross-sea network engineering plays a significant role in promoting regional economic integration, improving infrastructure levels, and driving technological advancement, making it the focus of this study. Despite the many benefits brought by cross-sea network engineering, there are also numerous challenges faced during its construction. For example, the construction of cross-sea bridges needs to overcome challenges, such as harsh natural environments and high construction difficulty, while submarine cable power transmission projects must address technical issues related to cable design, manufacturing, and construction (Li et al., 2022). As shown in Table 1, it is not uncommon for major cross-sea network projects to face delays exceeding one year. In recent years, the application of 3D virtual digital visualization technology in engineering has provided new solutions and methods for overcoming environmental and technical challenges (Sidani et al., 2021). At the same time, 3D virtual digital visualization technology is used to address practical problems in cross-sea network engineering, optimize project management, and enhance project quality, while also promoting technological innovation and the establishment of industry standards.
