摘要
///In this paper, the soil properties in different excavation zones were analyzed,and the hardening soil model was adopted to simulate the influence of excavation unloading and soil hardening.An actual excavation was numerically analyzed using finite element method,the earth pressure on retaining wall and lateral displacements of retaining wall were computed and compared with measured data.The results show that the numerical analysis with adopting hardening soil model can reflect unloading/reloading and hardening characters of soil,the computed results of earth pressure on retaining wall,lateral retaining wall displacements and basal stability factors coincide with experiential results of excavation in soft ground.
