【摘要】：通过东非某工程海上超长嵌岩灌注桩自平衡试验,探讨不同风化岩层的竖向抗拔侧阻力分布规律,得出如下结论:1)强风化砂岩侧阻力与位移拟合线性关系为:y=1.534 2x+180.48;2)中风化泥岩侧阻力与位移拟合线性关系为:y=0.954 5x+353.5;3)相对于中风化岩层,桩土相对位移对于强风化岩层阻力值更为敏感。
[Abstract]:Through self-balance test of super-long rock-socketed cast-in-place pile in East Africa, the vertical anti-uplift resistance distribution of different weathered strata is discussed. The following conclusion is drawn as follows: (1) the linear relationship between side resistance and displacement of strongly weathered sandstone is: 1: y = 1.534 2x 180.48 / 2) the linear relationship between side resistance and displacement of weathered mudstone is: 1: 0. 954 5x 353.5 / 3) relative to medium weathered strata. The relative displacement of pile and soil is more sensitive to the resistance value of strongly weathered rock.
