AI Technical Summary

Technical Problem

Quality control during bridge construction is lagging behind, making it difficult to monitor changes in the temperature field of concrete components and the influence of environmental temperature and humidity in real time. This leads to remedies being taken only after cracks appear. Control of construction deviations relies on manual measurement and is influenced by a single factor. Adjustments to construction plans are delayed, making it difficult to provide scientific guidance.

Method used

A bridge BIM model was constructed and a digital twin platform was built to collect real-time temperature field data, ambient temperature and humidity data, and laser point cloud data of concrete components. The cracking risk index, dynamic deviation index, and comprehensive carbon emission index were calculated. The construction plan was optimized through a three-level optimization decision tree strategy, and real-time monitoring and adjustment were carried out.

Benefits of technology

It enables real-time, dynamic monitoring and risk warning of concrete construction quality, improves the timeliness and accuracy of construction quality control, precisely controls construction deviations, provides scientific construction guidance, promotes green construction, and enhances construction quality and precision.
