摘要
从带预制桩尖的沉管灌注桩与混凝土预制桩同属于挤土桩的观点出发,在较为成熟的混凝土预制桩承载力参数和公式的基础上,提出了利用双桥静力触探方法确定沉管灌注桩单桩极限承载力公式和参数的方法,该方法的计算结果与实测值比较吻合,可在实际工程设计中应用。
For the pipe-sinking-filling pile with a sharp end and pre-cast concrete pile both belong to soilpushing pile, based on the pre-formed concrete pile parameters and formulas, we bring forward the method of determining the ultimate bearing capacity and parameters of single CPT. The calculation results of this method coincide with measured pipe-sinking-filling pile by Double Bridge data and can be applied in practical engineering design.
