Many large Australian infrastructure projects will be developed in regions with inherently poor soil conditions. Port developments, for instance, are by their nature located in river estuaries which are characterised by deep deposits of soft alluvial soils. Many highway projects also traverse low-lying ground or coastal regions with soft soil conditions. This project will develop a novel technique to improve the engineering characteristics of very soft soils (shear strength lower than 15 kPa) by using geogrid wrapped stone columns. The effectiveness of this technique will be investigated in both small scale laboratory tests and field trials.

澳大利亚许多大型基础设施项目将在土壤条件本来就很差的地区开发。 举例来说，港口的发展，就其性质而言，是位于河口，而河口的特点是有深厚的软冲积土沉积。许多公路项目还穿越低洼地或沿海地区的软土条件。该项目将开发一种新技术，通过使用土工格栅包裹石柱来改善非常软的土壤（抗剪强度低于15 kPa）的工程特性。这项技术的有效性将在小规模的实验室试验和现场试验中进行研究。
