Consolidation by vertical drains
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1981 <p>Building the embankment of traffic infrastructure (roads and railways) requires faster and more quality construction. One of the problems that often occurs in achieving these goals is the consolidation, which often occurs long after the completion of construction, resulting in subsequent settlements and damage to the roads.

Avoid construction failure by controlling settlement with a geosynthetic enchased geofoam granular column [PDF]
E3S Web of Conferences, 2023 Soils with low bearing capacity (soft soils) can cause the collapse of overlying structures. Before the superstructure is built, the soft soil needs to be improved first.

Consolidation analysis around cavity expansion in presence of vertical drains [PDF]
E3S Web of Conferences, 2023 As a ground improvement technique, the new method composed by a cylindrical cavity expansion (CCE) combined with vertical drains (VD) greatly accelerates the consolidation of soft soil. In fact, the cylindrical cavity applies a radial displacement in the
