Wick drains program features
A program for estimating wick drain assisted consolidation
times and settlements of surcharged compressible soils.
Consolidation of cohesive soils can be a very time consuming
process. Where desirable, the consolidation can be expedited by installing
vertical drains referred to as "wick drains". Wick drains work by
promoting horizontal dissipation of excess pore pressures instead of vertical
excess pore pressure flow in traditional 2D consolidation problems. In all
cases, the soil has to be subjected to a surcharge in order for the wick drains
to be effective. Hansbo (1979) has outlined a procedure to estimate
consolidation times for wick drain assisted consolidation.
Wickdrain 1.0 is a program that evaluates consolidation times and settlements
for wick drain assisted consolidation due to a surcharge according to Hansbo
(1979). The program also computes the required consolidation times for
traditional 2D consolidation for single or double drainage conditions.
Consolidation settlements are also calculated for both the recompression and
the virgin compression zones. Only one soil layer can be specified.
