文章通过１７组桩的原型荷载试验及计算，对钻孔挤压分支桩的竖向承载力进行分析与研究。研究结果表明：同一场地、相同桩长、相同桩径的钻孔挤压分支桩与钻孔灌注桩相比，仅增加６％～１５％的混凝土用量，而单桩竖向承载力却提高一倍以上。因此，钻孔挤压分支桩经济效益十分明显 This paper analyzes and studies the vertical bearing capacity of bored piles through the prototype load test and calculation of 17 piles. The results of the study indicate that the bored and extruded branch piles with the same site, the same pile length and the same pile diameter only increased the amount of concrete by 6% to 15% compared with the cast-in-place bored pile, but the vertical bearing capacity of the single pile increased by one. More than times. Therefore, the economic benefits of drilling and extruding branch piles are very obvious
