以塞尔维亚泽蒙—博尔察大桥主桥上部结构计算为依托,介绍了采用旋挖钻施工钻孔桩,比较了泥浆护壁施工工艺和可重复利用全护筒施工工艺的优缺点,我国企业和当地企业采用不同的施工工艺进行桩基施工,均取得了良好的效果,设计者和施工者可根据项目的具体情况决定采取何种施工工艺。
Based on the calculation of the superstructure of the main bridge of Serbia-Bormuca Bridge, this paper introduces the construction of bored piles by rotary drilling, compares the advantages and disadvantages of construction technology of slurry retaining wall and construction technology of reusable full casing. Local enterprises adopt different construction techniques for pile foundation construction and have achieved good results. Designers and constructors can decide which construction technique to adopt according to the specific conditions of the project.
