摘要：对东海大桥辅通航孔连续梁桥的施工控制作了简要介绍。对施工中的不确定因素，诸如边跨合拢方案和不同桥墩悬浇进度不一致等进行了分析比较。为了了解结构参数对施工控制的影响，在建立模型时，对结构参数选取了不同的数值，并对结果进行了分析比较。

Simple Study on Construction Control of Auxiliary Channel Continuous Girder Bridges of Donghai Bridge

WANG Fa-wu，SHI Xue-fei

Abstract: Construction control of auxiliary channel continuous girder bridges of Donghai Bridge is briefly introduced. Uncertain factors in construction of continuous girder bridge such as side span joint scheme and different balanced cantilever construction speed are analyzed. In order to find influence of structure parameters on construction control, different values are chosen in modeling and the results are analyzed and compared.
