Optimal Layout of Prefabricated Vertical Drains
Publication: International Journal of Geomechanics
Volume 15, Issue 3
Abstract
An approach to finding the optimal layout of prefabricated vertical drains (PVDs) in soft soil treatment, which has the minimum amount of PVDs and meets the requirements for the degree of consolidation, is proposed. Because explicit functions for settlement and consolidation in a multilayer ground for PVDs are not available, the current study uses the differential evolution method. The results show a stable relation between the optimal value with elapsed time, degree of consolidation, and embankment height.
