Research on the construction and monitoring applications of national highway bridge data platform

In order to solve the practical problems of improving the support for operational safety and maintenance management in the construction and monitoring application of highway bridge data platforms, and to meet the functional requirements of industry macro decision-making assistance, real-time operation monitoring, and emergency event supervision, this article proposes the construction method of the national highway bridge data platform, and proposes the overall framework, business framework, functional framework, and technical framework of the platform. On this basis, the application of highway bridge technical condition monitoring was studied, and the highway bridge technical condition forecasting technology based on long and short memory neural network and highway bridge safety assessment technology based on deep confidence network were proposed. Combining with the engineering application of the National Highway and Bridge Data Platform, the proposed technology for monitoring the technical condition of highway bridges has been validated with high accuracy and reliability, and has high application value. It provides a strong starting point for the supervision of highway bridge maintenance industry, and significantly improves the safety level of highway bridge maintenance and operation.
