There are no empirical parameters for soft rock geologic strata in Namibia oil tanker jetty.According to the in-site static tests and stress measurement results of one compression cast-in-situ pile and one compression-uplift pile,we analyze the mobilizations of skin friction and tip resistance in soft rock,and obtain the uplift coefficients of sand and silt at upper layers and the uplift ultimate bearing capacity of Q-s curves,which is characterized by slow variation.The test results show that,the relative displacement of pile and soil at upper layers is from 9 to 15 mm when the skin friction resistance of compressive pile gives fully play,and the ultimate value of unit skin friction resistance is from 30.1 to 48.1 kPa.The relative displacement of pile and soil is more than 40 mm when the skin friction resistance gives fully play in soft rock geologic strata.For the compressive process of two piles,under the maximum test load,the pile toe resistances are separately 22.3% and 27.3% of the pile head load.They act as friction piles because of small toe resistance.The ultimate bearing capacity of the uplift pile is 4 896.7 kN by using a hyperbolic model.
