In order to estimate the static axial capacity of driven piles, one-dimensional wave equation analysis was proposed in 1960, in which pile is simulated by a number of masses attached to each other using elastic springs, sliders and linear viscous dampers to simulate the visco-elasto-plastic response of the soil. Later, the signal matching technique program, CAPWAP, employing this model, was proposed to overcome the shortcomings of the conventional model. The main objective of this paper is to assess capabilities of so-called continuum numerical model in analyzing dynamic pile load test. In this paper, the static and dynamic load tests of an open-ended steel pipe pile driven into dense sand have been simulated using PLAXIS 2D finite element software. After carrying out a number of numerical analyses the results of numerical simulation have been compared to static load test results. The capabilities and challenges of the continuum numerical analysis to simulate dynamic pile testing of steel pipe piles are briefly discussed.
