Abstract
The volume of structural health monitoring (SHM) data is rapidly increasing due to the explosive growth of information from constructed infrastructures. However, data storage by different monitoring organizations is often isolated, even when they serve the same construction project, resulting in “data silos”. Improving the efficiency of sharing massive monitoring data and developing a reliable, distributed system can significantly enhance data mining efficiency. In this paper, a secure and anti-tampering data bank for sharing tunnel SHM data was innovatively constructed based on blockchain technology, significantly enhancing traceable storage, regulation, and collaboration between different organizations. A smart contract was implemented to manage heterogeneous data storage, monitor incremental calculations, and make alert judgments. A series of tests assessing traceability and applicability were conducted using monitoring data from a tunnel in Hangzhou, collected through Wireless Sensor Networks. The results demonstrate that the constructed data bank effectively facilitates data exchange and sharing among multiple monitoring parties.
