Abstract Cone penetration tests are more and more widely used in ocean engineering. Super long and large diameter piles are commonly adopted for constructing ocean platform foundations. The pile-run phenomenon frequently takes place because of the great weight of both the pile and the hammer. The American Petroleum Institute(API) recommendations are commonly used to assess the static pile bearing capacity，which is the sum of the pile end resistance and the shaft friction. The calculation method for estimating the soil resistance during pile-run is different from the static bearing capacity calculation and should be associated with practical engineering observation. Based on the cone penetration test(CPT) data，a procedure for calculating the soil resistance is put forward，in which the shaft friction is computed by using existed method and the tip bearing capacity computed by the improved Laboratoire Central des Ponts et Chaussées(LCPC) method. By comparing the soil resistance and the weight of the pile plus the hammer，the equilibrium conditions of pile-run can be established. The suggested method has been used to predict pile-up in a project in the South China Sea，and the calculated results agree well with the observed data，indicating that the proposed method may be helpful to the pile foundation designers in ocean engineering.

Key words： pile foundation long and large diameter piles pile-run soil resistance cone penetration test(CPT) sensitivity
