| 摘 要： | 根据４根桩底压力灌浆的钻孔桩的试验资料，从其荷载传递的特点（桩端阻一开始即参与承载，桩端阻和桩侧摩阻趋于同步发挥）出发，计算了不同桩顶荷载作用下极端阻的安全系数Ｋｂ和桩侧摩阻的安全系数Ｋｆ，以及Ｋｂ、Ｋｆ和桩项位移Ｓ／ｄ的关系，并和普通钻孔桩进行了对比，对Ｋｂ、Ｋｆ、Ｓ／ｄ的取值提出初步的建议。

| Abstract: | The analysis of grouted-pile's transmission of load shows that its point-bearing capacity acts on as soon as pile loaded, and the point-bearing capacity as well as the frictional resistance rises in approximate proportion. Based on four tests of grouted-piles in site, this thesis calculates the vertical partial factors of pile Kb and frictional partial factors of pile Kf, also the pile's uplifts S/d. The results of ill comparision with those of bored-pile have been demonstraied and the approaches for determing the Kb, Kf and S/d have presented. |
