移动模架逐段悬拼推进就位安装技术

摘要

Taking the second set of movable mould frame installation of a super-large bridge along some passenger special line,the paper intro-duces the top-pushing in-place installation technique of the piecewise cantilever of the movable mould frame,the crane lifting cantilever by bind-ing and pushing section by section,and points out the method can be adopted extensively,especially in some environment with special topograph-ic features,including mountains,valleys,rivers,lakes and spanning traffic routine.%以某客运专线铁路一座特大桥的第二套移动模架安装为例，介绍了移动模架逐段悬拼顶推就位安装技术，即吊车起吊悬拼，联结一节顶推一节的施工技术，指出该方法适用性广，尤其是用于特殊地形环境，如：桥址是深山峡谷、江河或湖泊滩地、跨越交通线路等。
