软土地基上高墩现浇支架设计

Design of Cast-in-Situ Scaffolding on Soft Ground for Construction of High-Rise Piers

润扬大桥南引桥具有地基软、墩高、跨径大等特点,为使引桥箱梁施工安全、经济、快速地进行,对基础、支架方案进行充分的比选和合理的设计。经充分的论证最终选用群桩加小承台基础和大直径钢管支架的设计方案。

The south approach spans of Runyang Bridge are characteristic of soft ground foundations, high-rise piers and long span. To ensure that the construction of the box girder of the approach spans can be carried out in a safe, economic and rapid way, their foundations and scaffolding are sufficiently compared, selected and reasonably designed. Following the thorough evaluation, the group piles plus small pier bases and large diameter steel pipe supports are chosen as the final design.
