Study on the Change of Deformation Modulus of Ho Chi Minh City’ Soft Soil Under the Extension Stress Paths for Deep Excavation Calculation
To predict the displacement and deformation of the deep excavation, it is necessary to determine the ground characteristics of the soil surrounding the deep excavation to include in the soil models. However, geological data for the design of the deep excavation is mainly obtained from conventional geological experiments, which have not yet described the behavior of the soil surrounding the excavation. Therefore, the problem is to use an experimental model with a reasonable stress path to determine the input parameters that match the behavior of the ground around the excavation pit, which is manifested by the changes in soil stiffness during the excavation work. This is what the current experimental protocol considers unchanged. This paper uses a triaxial test device to analyze the stiffness behavior of soft soil in Ho Chi Minh City (HCMC) according to the stress paths of extension in calculating deep excavation.
