A New Approach to Solution for Partially Penetrated Prefabricated Vertical Drains
Abstract Partially penetrated prefabricated vertical drains (PVDs) have been analyzed by many methods, including analytical methods, semi-analytical methods and finite element methods (FEM). The recent methods have considered the drain’s end as a permeable region while most of the current construction techniques use an anchor plate element at the end of a PVD, which prevents water flowing from the beneath untreated soil. This paper takes this practical situation into account and derives a semi-analytical solution for partially penetrated vertical drains. The results are also verified by FEM method using ABAQUS software. As a result, the excess pore pressure with depth obtained by the proposed solution is mechanically reasonable as compared with previous solutions and FEM. In addition, a subroutine of visual basic for application in Microsoft Excel is developed to easily obtain eigenvalues.
