Research Status and the Prospect of Cable-stayed System Reinforcement of Continuous & Rigid Box-girder Bridges

This scholarly article elucidates the prevalent pathological manifestations and underlying causes within the prestressed concrete continuous system bridges. It delves into the methodology of employing the low tower cable-stayed system to reinforce continuous system bridges. The low tower cable-stayed system reinforcement technique effectively mitigates beam deflection, augments the bridge's load-bearing capacity, and bolsters its structural integrity, thereby introducing an innovative paradigm for bridge reinforcement. Finally, the strengthening technology of the cable-stayed system of the low tower is prospected.
