Application of Durability Monitoring Technology to Cross-Sea Passage Project Structure

In order to ensure safe operation and maintenance of the cross-sea passage project and ensure the design service life of the cross-sea passage project, a design scheme for structure durability health monitoring was proposed based on the corrosion environment and structural characteristics of the cross-sea passage in combination with the engineering case of the Shenzhen-Zhongshan Link. In this scheme, 36 sets of durability monitoring sensors were selected and installed, and 5 sets of durability monitoring systems were successfully built. At the same time, the durability situation of the structure was analyzed in the early stage, combined with the data collected on site. The monitoring results showed that the structure of Shenzhen-Zhongshan Link was in good durability condition.
