Wet Mass Soil Mixing Applications in Geotechnical Engineering

摘要

This paper presents four applications where the wet mass soil mixing technique was used to solve different geotechnical problems. In the first application, wet soil mixing was used to improve the shear strength of the soil and increase the global stability factor of safety of a gravity retaining wall built near a man-made lake. In the second application, the same technique was used to build a structural support system for large combustion turbines and transfer large loads through soft organic materials to a competent and relatively shallow limestone layer. In the third application, wet soil mixing was used to build a 4.7-m-high gravity retaining wall at a Boeing aircraft hangar. In the fourth and final application, the technique was used to build a water cut-off box to permit the construction of large pile caps below the elevation of the water table.
