钢筋混凝土T梁桥病害处理措施与加固设计

钢筋混凝土T梁桥由于造价低、施工方便等特点,在低等级公路上普遍使用。然而,随着经济发展和交通量的增加,该桥型挠度大、裂缝多等病害也大量出现。根据太湖长河东门新桥在使用时期出现的病害,作出了详细的分析,提出了针对性的处理措施与加固设计方案,解决了桥梁运营的安全问题。该文就钢筋混凝土T梁加固改造问题做了较为深入的探讨和分析,对今后同类桥梁有指导意义。

Fault Treatment Measure and Reinforcing Design of Steel Reinforced Concrete T-beam Bridge

The steel reinforced concrete T-beam bridge is commonly used in the low-class highways because of its low construction cost and convenient construction. With the increment of economical development and traffic flow, many faults of this bridge also happen, i.e. great deflection and many cracks. According to the faults of Tai River Changhe Dongmen New Bridge under operation, the article analyzes these faults in detail and puts forward the special treatment measure and reinforcing design scheme to solve the security problem of bridge operation. The article deeply discusses and analyzes the reinforcing reconstruction problems of steel reinforced concrete T-beam and provides the guiding meaning for the same bridges in the future.
