| 摘 要： | 本文介绍了嘉兴软土地基中微型桩单桩和群桩的抗拔试验,试验表明微型桩能承受一定的抗拔力,尤其是斜桩基础能有效地减少竖向拉力引起的位移,微型桩群桩表现出更好的抗拔性能。该文将试验结果与现有抗拔桩承载力公式计算值进行了比较分析,探讨了微型桩直桩和斜桩的抗拔系数以及群桩效应系数,为其今后的工程设计和应用提供一定的参考。

| Abstract: | The full scale tests for the single micro-pile and micro-pile groups used in soft soil under uplift loading in Jiaxing are introduced.The testing results indicate that micro-piles can resist uplift loading.Especially,the angled micro-piles can decrease the displacement caused by uploading.The testing results for the uplift capacity of micro-piles are compared with the results from the calculation by using experienced formula,and the coefficient of the uplift for the vertical micro-piles and the angled piles and the coefficient of pile group efficiency are discussed. |
