| 摘 要： | 进行了2根H型钢桩的现场原型试验,桩长分别为39．6m和55．4m,单桩设计承栽力为3540kN。沿桩身布设了应变计后,桩通过锤击方式打入到密实砂土层中。观测了桩在不同荷载水平下的荷载传递及沉降特性。并用土力学原理对实测桩侧摩阻力的大小和分布进行了检验。 |

| Abstract: | This paper presents results of full-scale loading test on two steel H-piles driven into dense sandy de- posits.The tested piles,with the embedded length of 39.6m and 55.4m respectively,have a design capacity of 3540kN.Both piles were heavily instrumented,driven into very stiff strata and loaded to failure.The load transfer and settlement characteristics of the piles are examined for various loading levels.The magnitude and distribution of the shaft friction of the piles are analyzed using the principles of soil mechanics. |
| Keywords: | Pile capacity Load transfer Sandy soil Field tests |
