| 摘 要： | 通过分析套箍和砌体横向应变关系,探讨了采用钢筋昆凝土套箍加固石拱桥对核心砌体的约束机理,并提出了套箍对核心砌体的约束应力及由于套箍约束作用使砌体强度提高的计算方法.同时,通过此方法对巴中市南江县龙渠大桥进行了加固设计,计算后得知主拱圈承载力得到明显提高,且实际运用效果良好.

| Abstract: | By analyzing the transverse strain relationship of yoke and masonry,the constraint mechanism to the core masonry is explored when reinforcing the stone arch bridge by reinforced concrete yoke,and the calculation methods are proposed for the constraint stress to the core masonry caused by the yoke and the improved strength of the masonry caused by the yoke.Meanwhile,through this method,the reinforcing design is made for Bazhong Nanjiang Longqu Bridge.The results show that the main arch capacity has been mark... |
