AI Technical Summary

Technical Problem

Existing technologies struggle to quickly and accurately predict and control the torsion angle at the cantilever end of curved bridges during the cantilever construction phase, making it difficult to guarantee construction safety and the quality of the completed bridge's alignment. Furthermore, they suffer from low computational efficiency and difficulties in parameter sensitivity analysis.

Method used

By obtaining the bridge's stiffness, section moment of inertia, section shear modulus, section torsional constant, and the self-weight of the cantilever curved bridge structure, the trigonometric series of the deflection and torsion angle at the cantilever end can be directly calculated using the trigonometric series calculation module for undetermined coefficients, thus achieving rapid analytical solution acquisition.

Benefits of technology

It improves the computational efficiency and engineering applicability of predicting the torsion angle at the cantilever end, simplifies parameter sensitivity analysis, and supports rapid calculation in the design phase and real-time control on the construction site.
