高速公路高墩大跨度刚构连续梁0#块牛腿托架法施工技术

Construction Technology of Expressway High Pier Long-span Rigid Frame Continuous Beam 0# Block Corbel Bracket

高墩大跨度刚构连续梁0#块托架设计是连续梁施工的关键所在,本文详细阐述了高墩大跨度刚构连续梁大体积0#块牛腿托架法施工的设计思路和托架受力计算,并通过现场实际施工论证了牛腿托架法在高墩大跨度连续梁大体积0#块施工的安全、经济、合理性。为今后大跨度高墩连续梁0#块托架设计与施工积累了经验,并为同类结构的设计提供参考与借鉴。

High pier long-span rigid frame continuous beam 0 # block bracket design is the key to construction of continuous beam.This article expounded the design idea and bracket stress calculation of high pier long-span rigid frame continuous beam 0 # block corbel bracket construction, and demonstrated the safety, economy and rationality of corbel bracket method in high pier large span continuous beam mass 0# block construction. This paper accumulates experience for the design and construction of large-span high pier continuous beam 0# block bracket, and provides reference for design of similar structures.
