振动沉管灌注桩施工质量问题及其防止方法
【摘要】 振动沉管桩以其成极效率高.承载能力强、超径系数小、工程成本低、桩长控制灵活等优点而得到广泛应用。但是,它的施工工艺很复杂,稍有疏忽就会导致各种施工质量问题。本文就这些问题作出一定的分析研究,并提出相应的防止方法和措施,以供同行参考。
【Abstract】 Vibro-sinking cast-in-place pile is widelY used because it has many advantages.However, the problems about the construction quality are possible to happen because of thecomplicated constructive technique. This paper analyses these problems and proposed correspondingprevent methods and measures.
