Slope Stability of Embankments on Soft Soil Improved with Vertical Drains

Settlements and Consolidation Rates under Embankments in a Soft Soil with Vertical Drains

In this paper, a study was carried out in order to estimate settlements and consolidation rates under embankments constructed on Moroccan soft soils.  Settlement measurements in several embankments in High Speed Railway project between two Moroccan cities, Tangier and Assilah,  were analyzed. The objective of this study is to estimate settlement values and settlement rates, with sufficient prec...

Three-Dimensional Analysis of Soft Soil Consolidation improved by Prefabricated Vertical Drains

A system of prefabricated vertical drains (PVDs) with a surcharge load is an effective method for accelerating soil consolidation by promoting radial flow. This study presents a three-dimensional (3D) finite element model for soft soil improved by a single drain. In the finite element analysis, the actual rectangular PVD cross-section is considered, and the equivalent drain diameter is then bac...

Soft soils improved by prefabricated vertical drains: performance and prediction

Load-factor Stability Analysis of Embankments on Saturated Soil Deposits

A continuum-based finite-element methodology is established for quantifying the stability of earthen embankments built on saturated soil deposits. Within the methodology the soil is treated as a fluid-solid porous medium, in which the soil skeleton’s constitutive behavior is modeled using a smooth elastoplastic cap model that features continuous coupling between deviatoric and volumetric plasti...

Bridge foundations supported by EPS geofoam embankments on soft soil

EPS geofoam can be used to support highway bridge structures without the aid of deep foundations. The development of this technology is important to accelerate construction on soft compressible soil. EPS geofoam allows for the rapid construction of bridge foundations on such soils without the time and cost involved in installing traditional foundations. Because EPS geofoam is an extremely light...
