特大桥预应力混凝土连续箱梁满堂式碗口支架方案设计

Full Space Bowl Shaped Support Scheme Design of Super-Large Bridge′s Prestressed Concrete Continuous Box Girder

混凝土连续箱梁施工中,支架为桥梁上部提供了施工平台,同时也是重要的支撑体系,其安全性必须得到充分保证。依据设计图纸和现场实际情况,设计了满堂式碗口支架的方案,并对方案进行了验算。

In construction of concrete continuous box girder, the support provides the construcuon ylau for the upper part of the bridge, which is also the important support system. So its safety must be ensured. On the basis of the design drawing and the real conditions of the field, the full space bowl shaped support scheme is designed and the scheme is checked at the same time in the paper.
