The knowledge of the effects on existing supporting structures performances due to deepen excavation of foundation pits are necessitated to avoid the occurrences of invalidating supports or conservation designs. This paper proposed an analysis model with Finite Element Method (FEM) to dynamic simulate the gradually varieties of earth-structure association and construction load and their inter-influences. The key techniques of establishing the model, including selection of simulated archetype, simulating methods, and processes designs of staged construction, are discussed through proposing an i...
