大跨度预应力砼连续梁梁式支架现浇施工技术

Construction Technique of Great Span Pre-stressed Concrete Continuously Beam Style Support Cast-in-place

介绍了蒲坝安宁河特大桥预应力混凝土连续梁以"八七"型军用梁作为支架进行混凝土浇筑,取得了成功,创下目前四川省乃至全国采用梁式支架浇筑跨河桥梁中跨度最大的记录。该技术成果将混凝土现浇梁式支架跨度提高到一个新台阶。

Puba Arming River Superlarge Bridge pre-stressed concrete continuously beam carries on concrete construction by ＂87＂ type military beam as the support, which has achieved great success. And it has set the biggest span record of constructing the cross river bridge with the beam type support in the present Sichuan Province and even the whole nation. This technique result will promote the concrete cast-in-place beam type support span to a new phase.
