In this paper, the results from three-dimensional analysis of offshore driven pipe piles using FLAC3D (Fast Lagrangian Analysis of Continua in three dimensions) program were presented.Abstract:
This paper presents the results from three-dimensional analysis of offshore driven pipe piles using FLAC3D (Fast Lagrangian Analysis of Continua in three Dimensions) program. The numerical model was developed with solid elements for both the pile and the surrounding soil. Interfaces are created both on the inside and outside surfaces of the pipe pile along the length as well as at the bottom of the annular area of the pile. The pile driving was simulated by giving hammer impact force of one blow which was measured during offshore pile installation. Parametric studies were performed with different soil properties until the signals from the numerical analyses matched with the measured force–velocity data of the pile installed in offshore South East Asia region. The results include the soil plug behaviour under continuous driving and with a delay time of 12 h.read more

Pile-Driving Analysis by the Wave Equation
TL;DR: All pile-driving formulas, used at present time, are partly empirical and apply only to certain types or lengths of pile; mathematical method of wider application, depending on use of electronic computers and numerical integration is presented; pile must be divided for calculation into unit lengths considerably shorter than wavelength of stress or impact wave produced by hammer as mentioned in this paper.

Application of a continuum numerical model for pile driving analysis and comparison with a real case
TL;DR: In this paper, an axisymmetric finite difference numerical model is developed having solid elements for both pile structure and the soil media surrounding and below the pile to facilitate the sliding between the two media.

A continuum method of pile driving analysis: Comparison with the wave equation method
TL;DR: In this article, the authors used a continuoustime method of finite element analysis to predict the behavior of a steel pipe pile during driving, where both the pile and the soil are treated as two distinct parts of the same solid continuum, with different properties.
