GGU-CONSOLIDATE: Test 7 - Consolidation (numerical) with vertical drains and actual pore water pressure distribution and time-dependent loading function

In analogy to Test 6, a two-layer system will now be investigated. Select the following preferences from the menu item "Edit/Type of consolidation":

In "Edit/System parameters", enter the following values:

Input for soil properties, pore water pressure distribution and load increases are analogous to Tests 2 to 4. The easiest way is to load the file for Test 4.

Boundary conditions can not be applied for numerical modelling of vertical drains.

The analysis shows that - after the tipping time of 100 days is complete - 80% of settlements have occurred after a further lying time of only 10 days. This is still too long for the client.

Complete soil replacement is currently planned within the protection of a complex sheet pile wall structure. The replacement material has a permeability of > 1 · 10^-5 m/s.

Apart from the substantial reduction in absolute settlements, a projection of the time-settlement profile shows that 99% of settlement has already occurred after approx. 2 hours. Can we live with this?
