| 摘 要： | 开裂是混凝土及圬工拱桥使用过程中的常见现象,是其损伤开始的标志.鉴于空腹式无铰拱桥开裂荷载研究不充分的现状,在总结拱桥破坏规律的基础上,提出对称荷载破坏、偏载破坏两种基本破坏型式,使用悬索线拱桥理论推导了其开裂荷载的实用表达式,为实际拱桥状态的快速评定提供理论依据 |
| 关 键 词： | 开裂荷载 破坏型式 悬索线理论 |

| Abstract: | Cracking was a normal phenomenon in concrete and masonry arch bridge, which was a symbol of damage started. Because of the insufficient research work on computing method of open-spandrel hingeless arch bridge cracking load, a practical method for this type arch bridge was proposed in this paper. Based on failure law of higeless arch bridge, the two failure patterns （symmetric failure pattern, non-symmetric failure pattern） were proposed, and a practical method was deduced by using catenary arch bridge theory, which can be used in suitable arch bridge assessment. |
| Keywords: | cracking load failure pattern catenary arch bridge theory |
