Based on the literature research, the method which integrates Monte Carlo simulation technique and finite element method was used to quantify the reliability of rock-socketed steel pipe pile during construction considering pile-soil interaction behavior and uncertainties in various variables. Uncertainties associated with horizontal foundation coefficients, rock-socketed length, section properties of the pile and load conditions were explicitly considered. Combining with the result of the reliability analysis, fuzzy theory was used to calculate the direct economic loss of pile during construction. The probability of pile loss of different degrees was obtained through calculation and a comprehensive and systematic risk analysis for the construction period of the deepwater pile foundation was carried out.
