对佛山澜石大桥刚架拱桥病害进行了详细分析。根据分析结果与加固计算结果,提出了在弦杆和拱肋实腹段受拉区粘贴碳纤维、在大小结点处粘贴钢板及横系梁用角钢加强的加固方案。

The symptom of Foshan Lanshi rigid frame arch bridge is analysed in detail, and the strengthening design scheme is presented according to analytic and computing results. The scheme includes three main parts: affixing carbon fiber to the tensile region of the chord member and the arch rib's soffit, affixing steel sheet to the joint of the chord member and the knee brace and the joint of the chord member and the arch rib, and strengthening the tie beam with angle steel.
