给出用FRP材料加固的石拱桥的破坏模式及其极限荷载的估计方法。采用有摩擦单面接触有限元模型来模拟可能出现的裂缝。采用FRP材料加固拱腹和/或拱背,加固后拱的破坏模式有:石块滑移、石块压溃、FRP材料剥离及FRP材料断裂。计算得出的破坏模式与有关文献中给出的实验结果相同。
The failure mode of the stone arch reinforced with FRP material and the method of estimating the ultimate load are given. Frictional single-sided contact finite element models were used to simulate possible cracks. The FRP material is used to reinforce the soffit and / or arch, and the failure modes of the arch after reinforcement include: block slipping, block crushing, FRP material peeling and FRP material breaking. The calculated failure modes are the same as the experimental results given in the literature.
