摘要
沉桩困难是打入式桩基施工中经常面临的主要问题之一。由于受到众多因素的影响,目前对沉桩难易程度的分析仍停留在定性分析的基础上[1],①,很难建立完善的数学模型对该问题进行定量分析计算。本文结合工程实践,利用静探指标建立了一定条件下计算预应力高强混凝土管桩(PHC桩)沉桩锤击数的经验公式,为该桩型沉桩难易程度分析提供一种定量的分析方法,从而为桩型和沉桩设备的选择提供较为可靠的依据。
The difficulty of pile driving is one of the main problems which often occur during the construction of driving piles. Affected by many factors the method to analyze the pile driving is still based on the qualitative analysis, and it is very difficult to set up a consummate mathematical model for the quantitative analysis. Through engineering practice an experiential formula for the calculation of the driving numbers of PHC piles under some special conditions is set up, which offers a quantitative method to analyze the possibility of pile driving and a reliable method for the selection of the pile type and the driving equipment.
