چکیده
This study evaluated the use of Asaoka and hyperbolic methods to estimate ultimate settlement soft ground treated by vacuum preloading combined with prefabricated vertical drains. For this aim, a large-scale physical laboratory model was constructed. The reinforced-tempered glass box containing soil mass dimensions 2.0 × 1.0 1.2 m (length width depth). Physical models scale for same purpose are rare in literature. taken from typical coastal region Dinh Vu Hai Phong, Vietnam. surface near between two drains measured right after started. Important properties were tested evaluate effectiveness treatment method. used predict potential settlement. results showed superiority consolidation approach improving fundamental engineering soil. Furthermore, predicted both good agreement value, proving that suitable estimation consolidation.

Improving Engineering Properties of Soft Soil Using Preloading and Prefabricated Vertical Drains
Preloading and Prefabricated Vertical Drains (PVD) is a ground improvement technique used to increase the consolidation process of clayey soils by means of shortening the drainage path. This paper discusses a case study of a road construction where a part of road alignment goes through a low laying water logged area. Primary consolidation of soft clay will continue for longer period of time aft...
متن کاملEffects of partially penetrating prefabricated vertical drains and loading patterns on vacuum consolidation
In this study, numerical modeling of a multi-drain system is employed to determine the optimum penetration depth of prefabricated vertical drains (PVDs) and the vacuum pressure that provides the maximum consolidation settlement and less lateral displacements. The plane strain analysis using an equivalent permeability with transformed unit cell geometry was considered for varying drain length an...
