Abstract:: The overturning stability of a swing bridge structure is a key factor in ensuring its safety. Based on a cross-over rotating bridge project along the Taihang Expressway, this paper derives mechanical equilibrium equations under large and small eccentricity conditions through load-bearing tests. It quantifies the relationship between spherical hinge friction moments and structural unbalanced moments, and analyzes the anti-overturning mechanism of rotating structures. By investigating the stress characteristics of rotating bridge structures under different conditions, it reveals the influence patterns of unbalanced moments and unbalanced traction forces on the stability of horizontal T-shaped bridge structures. Results indicate that under project conditions, structural displacement increases abruptly when unbalanced moments exceed 25,600 kN·m or traction forces reach 6,600 kN. This causes significant stress concentration at spherical hinges, reducing the overturning stability factor below 1.0 and triggering structural buckling instability. Based on field measurement data and mechanical response analysis, the critical unbalanced moment and critical traction force for the rotating bridge structure were quantitatively determined to be 29,822.6 kN·m and 6,689.0 kN, respectively. This study reveals the critical state criteria for structural overturning instability, providing a scientific basis for the safe design and construction management of rotating bridges
