| 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: | The distributing law of shaft friction about weathered rock is discussed based on super-long rock-socketed piles self-balanced load test in a hydraulic dock in east Africa and the conclusions are as follows:Firstly,the uplift shaft resistance of highly weathered rock y=1.534 2x+180.48;Secondly,the uplift shaft resistance of moderate weathered rock y=0.954 5x+353.5;Furthermore,compared with the moderate weathered rock,the shaft resistance about highly weathered rock is more sensitive about the relative displacement between piles and soils. |
