| 摘 要： | 通过桩基静载试验实测数据,分析了桩身轴力的荷载传递机理.结果表明:桩顶荷载主要通过桩侧摩阻力逐渐向下传递,具有明显的摩擦桩特点,桩侧摩阻力所占比重较大,而桩端阻力所占比重较小;桩底沉渣厚度显著影响桩顶沉降量与极限承载力.

| Abstract: | Based on the in-situ test data of bored piles,the mechanism of axial load transfer was analyzed.The result shows that the load at the top of piles transfers downwards by means of lateral friction along piles,thus,such type of piles is of evident characteristics of friction piles.It is also demonstrated that the lateral friction accounts for large proportion,while the resistance at the end of piles accounts for small proportion,and that the sediment thickness at the bottom of piles evidently affects the top settlement and ultimate bearing capacity of piles. |
