摘要
钻孔灌注桩承载力取决于桩体几何尺寸、侧阻力及端阻力 ,分析了影响钻孔灌注桩承载力充分发挥的因素 :沉渣、泥皮厚度及孔壁形状等。说明了后压浆技术在钻孔灌注桩施工中提高单桩承载力的机理 ,并引入侧阻力影响系数及端阻力影响系数 。
The bearing capability of cast in place bored piles is determined by the size of the pile, side resistance and end resistance. Through the analysis on the elements influencing the bearing capability such as settlement, mud thick and shape of hole wall the mechanics adopting post grouting technology to enhancing bearing capability of single pile are elaborated and the side resistance coefficient and end resistance coefficient are introduced. At last the calculation method for single pile bearing capability of post grouting cast in place bored piles is put forward.
