Observation on Consolidation Settlement of Ground Improved by

Sand Compaction Pile (SCP) was adopted in order to mitigate liquefaction of upper granular soil layer and accelerate consolidation settlement of cohesive soil layers. A combination of Prefabricated Vertical Drain (PVD) and Dynamic Compaction were also adopted for the same purposes as SCP. Settlement was monitored after raising the embankment.

Prefabricated Vertical Wick Drains

Prefabricated Vertical Drains, also known as Wick Drains, are used to accelerate the consolidation of compressible soils. The consolidation of compressible soils involves the removal of pore water from the soil. This is traditionally done by applying a surcharge of preload to the construction area to “squeeze” the water out.

Optimal design of prefabricated vertical drain-improved soft

Jan 18, 2020 · Prefabricated vertical drains (PVDs) are widely used to accelerate the consolidation process within soft ground. The overall degree of consolidation (DOC) of soft ground is highly dependent on the arrangement of PVDs, such as their length and spacing. Nevertheless, only the ranges of spacing and length are recommended in codes and standards, which renders it difficult for designers to ...

Improvement of Coir Reinforced Clay Soil by Natural and

Sand drains are basically boreholes filled with sand. The installation causes disturbances, especially in soft and sensitive clays, which reduces the shear strength and horizontal permeability. Prefabricated Vertical Drain is a prefabricated material consisting of a plastic core covered by synthetic geotextile filter jacket.

Ground Improvement Optimization with Prefabricated Vertical

within schedule. Prefabricated vertical drains (PVD) have been generally used to decrease the overall time required for comple tion of primary consolidation by shortening the drainage path length. PVD has largely replaced other drainage techniques due to its advantages of economic competitiveness, less disturbance of the soil mass, speed and

Prefabricated Vertical Wick Drains Installation

In the vertical application, the wick drains are installed with specialized equipment that drives the strips of wick drain into the ground. Vertical wick drains, in conjunction with a preload, provide a drainage path for water-saturated areas to speed up settlement. Saving the project time and money compared to a preload alone or having to use ...
