摘　　要：针对现浇连续箱梁采用墩梁式支架,介绍了临时支墩的构造和特点,利用ANSYS软件,建立了支墩的整体力学模型,通过计算得到了其整体稳定安全系数,计算表明所组拼的临时支墩具有较高的整体稳定安全系数,满足施工要求。可供同类施工结构设计参考。Owing to the fact that cast-in-place continuous box girders are supported with pier-beam-type supports, the structure and characteristics of the temporary supporting piers are dealt with in the paper, and a mechanical model for the whole supporting pier is established with the help of the software ANSYS, through which the stability coefficient of the whole pier is worked out by means of calculation. The result of the calculation shows that the assembled temporary supporting pier is comparatively stable as a whole, and can meet the construction requirements. It may serve as a useful reference for the design of the structures of the same type.
