摘要：
The design approaches to prefabricated vertical drains (PVDs) for different geotechnical and geoenvironmental engineering applications involve converting the PVD's rectangular band shape to an equivalent circular shape to simplify the analytical analysis. Several equivalent diameter equations for PVDs are available in the literature. However, these equations produce different equivalent diameters and no definitive recommendation is available regarding their validity. The aim of this study is to assess numerically the validity of these equations and identify the most appropriate one for use in design.
