钻孔灌注桩作为一种基础形式以其适应性强、成本适中、施工简便等特点被广泛地应用公路桥梁及其它工程领域。由于其隐蔽性和基础工程的重要性特点,钻孔灌注桩的质量直接影响上部结构的稳定和安全。本文主要从影响钻孔灌注桩施工质量的关键因素着手,分析钻孔灌注桩基础的缺陷原因,并提出了相应的防治措施。
As a basic form, bored pile is widely used in highway bridges and other engineering fields due to its adaptability, moderate cost and simple construction. Because of its hidden nature and the importance of basic engineering features, the quality of bored piles has a direct impact on the stability and safety of the superstructure. In this paper, the key factors influencing the construction quality of cast-in-place bored piles are mainly analyzed, the reasons of the defects of cast-in-situ bored pile foundation are analyzed, and the corresponding prevention measures are put forward.
