摘　　要：外滩大桥主桥为一座独塔四索面异型斜拉桥,跨径布置为(225+82+30)m,为了解在荷载作用下桥梁的实际工作状态,对该桥进行了静、动载荷载试验。试验结果表明:桥梁实际强度、刚度和承载能力满足设计及规范要求;桥梁工作性能满足设计和安全运营要求。通过荷载试验为大桥现状做出了科学客观的评价,同时也为今后同类型桥梁结构的发展积累经验和数据。The main bridge of the Waitan Bridge in Ningbo is an irregular shape cable-stayed bridge with a single pylon and four cable planes and with span arrangement（225＋82＋30） m.To have an understanding of the actual working conditions of the bridge under the action of loads,the static and dynamic load tests were made for the bridge.The results of the tests demonstrate that the actual strength,rigidity and carrying capacity of the bridge can satisfy the design and code requirements and the working performance can also satisfy the design and safe operation requirements.The load tests as mentioned give scientific and objective evaluation of the conditions of the bridge and accumulate experiences and data for the future development of the bridge structures of similar kind.

关 键 词：斜拉桥 静载试验 动载试验
