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.
