| 摘 要： | 近年来,对扩底抗拔桩和桩侧注浆抗拔桩这两种新型抗拔桩承载特性的研究受到广泛关注。依托上海虹桥综合交通枢纽工程,开展了等截面、扩底和桩侧注浆3种桩型抗拔桩的现场足尺对比试验。比较了各桩型桩侧摩阻力发挥特性的差异;并对典型土层在不同桩型中摩阻力的发挥特性进行了分析;将3种桩型抗拔桩的桩侧摩阻力实测值与规范推荐值进行了比较。进一步认识了软土地区扩底抗拔桩和桩侧注浆抗拔桩各自的荷载传递特性。

| Abstract: | Recently,the study on the bearing capacity characteristics of base-enlarged and side-grouted uplift piles has been highlighted.Take the Shanghai Hongqiao comprehensive communication hub project as the background,the full-scale site tests of straight-shaft,base-enlarged and side-grouted uplift piles are carried out.The features of side resistance of three kinds of uplift piles are compared,and then,the friction properties of the same layer in different uplift piles are analyzed.The measured results of pile-s... |
