【摘要】：通過東非某工程海上超長嵌巖灌注樁自平衡試驗,探討不同風(fēng)化巖層的豎向抗拔側(cè)阻力分布規(guī)律,得出如下結(jié)論:1)強風(fēng)化砂巖側(cè)阻力與位移擬合線性關(guān)系為:y=1.534 2x+180.48;2)中風(fēng)化泥巖側(cè)阻力與位移擬合線性關(guān)系為:y=0.954 5x+353.5;3)相對于中風(fēng)化巖層,樁土相對位移對于強風(fēng)化巖層阻力值更為敏感。
[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.
