随着短线匹配预制安装工艺在大跨径变截面连续刚构桥施工过程中逐渐推广;同时连续刚构桥跨度逐渐增大;导致墩顶块结构越来越复杂。本文依托港珠澳大桥香港接线高架桥,对高大复杂壳体墩顶块短线匹配预制工艺进行简述。
With the short-term matching prefabrication process gradually extended in the construction process of large-span continuous rigid frame bridge with variable cross-section; meanwhile, the span of continuous rigid-frame bridge gradually increases; the structure of pier top block is more and more complicated. This article relies on Hong Kong-Zhuhai-Hong Kong Bridge viaduct bridge, high-complex shell pier block short-term matching prefabrication process are briefly described.
