现浇高箱梁支架跨过暗河设计及施工技术

Designing and Constructing Technology for Cast-in-site High Box Girder Stents Across the Underground River

满堂支架的稳定性是影响箱梁质量的重要因素之一,而地基承载力是否满足支架稳定性是支架是否实施的关键因素之一。吉茶高速公路k27+000～K27+150现浇高箱梁跨越暗河,通过对该现浇高箱梁支架和跨暗河方案的设计、计算和实践,对满堂支架在复杂地域施工,提供了借鉴和参考作用。

The stability of the bunch stents is one of the important factors to influence the quality of box girder,and whether the bearing capacity of foundation can support the stents is one of the key factors for implementation.The cast-in-place high box girder located in the Jicha expressway k27＋000~k27＋150 is crossing the underground river,through the design、calculation and practice for this Scheme,it can provide reference that how bunch stents work in complex regional construction.
