摘要
通过改变管桩桩长,研究了2根不同桩长闭口管桩的贯入机制。试验结果表明,随着沉桩深度的增大,桩长越长压桩力越大,桩长对沉桩终压力的影响程度较大。随着沉桩深度的增加,桩周土的侧压力逐渐增大,桩-土间相互摩擦作用增大,进而桩侧摩阻力增大。
The penetration mechanism of two closed pipe piles with different pile lengths is studied. The experimental results show that with the increase of the depth of the pile, the longer the pile length, the greater the pile pressure,and the impact of the pile length on the final pressure of the pile is greater. With the increase of the depth of the pile,the side pressure of the soil around the pile gradually increases;the friction between the pile and the soil increases;the friction resistance of the pile side increases.
