The use of the Enviro-Wall-Mat in soft soil conditions for marshalling areas, crane hard stands and lay down areas-PPT Presentation

PPT Presentation

Pdf Summary

The Enviro-Wall-Mat combines the Enviro-Mat soil-stabilization system with trench-formed walls to improve ground performance in very compressible soils. Enviro-Mat is made by mixing a Geosta additive and cement into the existing soil, creating a strong, flexible layer that spreads loads and increases bearing capacity. For the wall system, trenches are excavated to depths of up to 15 metres and filled with low-strength concrete slurry.<br /><br />The system is intended for heavily loaded areas such as crane hardstands, laydown areas and marshalling yards, as well as other infrastructure requiring upgraded ground bearing capacity.<br /><br />Plaxis 3D simulations and a field test at Zeewolde assessed the system under simulated crane loading. The test recorded limited deformation after six hours. The presentation concludes that the walls can reduce settlement by approximately a factor of ten, and that the Plaxis model’s predicted deformation pattern was consistent with field results.<br /><br />Further study could optimize the wall material, spacing and width.
