摘要：
The aim of this paper is to present some case studies of deep excavations in Luanda down town, where the geological and geotechnical conditions are very complex, mainly due to surficial location of the ground water table, installed on granular and high permeability soils. The adopted solutions allowed the control of the deformations both at the earth retaining structures and at the neighborhood structures and infrastructures, as well as the control of the ground water inflow to the excavation pit, allowing the safe fulfilling of both the works schedule and budget.
