Discussion of "Numerical assessment of equivalent diameter equations for prefabricated vertical drains"

Abstract

The Discussion revises the figure that compares different equivalent-diameter equations for prefabricated vertical drains, and the result of another equivalent equation that has been widely used in practice is also added into the figure. In addition, a three-dimensional (3D) numerical model is developed to compare with the two-dimensional (2D) numerical model used in the paper. The result indicates that the difference between the 3D and 2D models can be about 5%.
