Accurate prediction of wall displacements induced by deep excavations is essential to guarantee stability and safety of the excavation as well as to prevent any harm and damage to the adjacent structures. This paper proposes and validates a set of equations for determining soil parameters of hardening soil model with small-strain stiffness (HS-small model) for medium dense sand in Ho Chi Minh City (HCMC), Vietnam. The study was based on back-analysis of diaphragm walls’ displacements from three…
