摘要
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。
In this paper we study the vertical bearing pressure of new model drilling pile with squeezing branch carefully.In this process we have made seventeen sets of prototype load tests and calculations. The results demonstrate that in the case of the same site and pile length and pile radius, compared with drilling pile,the concrete consume of new model drilling pile with squeezing branch only increases by six to fifteen percent, but the vertical bearing pressure of single pile increases by over 100%,So that the new model drilling pile with squeezing branch is reliable in technology. The economic profit is obvious.
