| 摘 要： | 以清代陆安(石拱)桥的整体搬迁工程为背景,通过非线性有限元方法,考虑了拱圈、拱墙和拱背填料等各个部分的空间共同作用,及石材开裂对结构刚度的影响以及填料与拱圈之间的粘结滑移效应,对桥体进行了结构分析。结果表明,陆安桥满足现行规范的要求,并具有较大的强度储备。结论对同类实腹式单跨石拱桥的保护研究具有参考意义。

| Abstract: | In order to protect cultural relics in the Three Gorges,a nonlinear analysis with the finite element method was evaluated.The nonlinear behavior of the masonry cracking and the effect of the slip between different materials were considered,including the effect of the space concerted action induced by the arch ring,the arch wall and the infill.It is shown that the Lu'an masonry arch bridge satisfied the correlative codes and had enough spare strength.The conclusions may be benefit for the conservation of the similar solid masonry arch bridge. |
