公路桥梁摩擦桩人工挖孔砼护壁优化设计与施工

Optimization design and construction about manual well concrete piles' breast wall of highroad bridge friction pile

文章以贵州境内三穗至凯里高速公路寨头II号大桥摩擦桩护壁优化设计与施工为例,阐述了桥梁桩基穿越不良地质地段时摩擦桩人工挖孔护壁的优化方法,以供同类工程参考。

Taking the optimization design and construction about friction pile＇s breast wall of Zhaitou Ⅱ bridge in the highway from Sanhui to Kaili in Guizhou province as the example, this paper expatiates the optimization method about manual well concrete piles＇ breast wall of friction pile when the bridge pile foundation drills through bad geology, so as to be references for similar projects.
