3-D FEM Analysis On Cantilever Cement-Soil Multiple-arch Combined Strutted Structure

With development of our country economics, all kinds of underground buildings and high-rise buildings are appeared in the city. Deep Excavations become the significant problems in the field of engineering.Firstly, basic theories of excavation and strutted system are summarized and reviewed in the paper. Common analysis method for cement-soil multiple-arch combined strutted structure is discussed. And two advanced analysis methods are compared.Cement-soil multiple-arch combined strutted structure is the new strutted system. Application and research for this field are seldom reported, especially for cement-soil multiple-arch combined strutted structure. According to the need of practical project, the assumption and reason distribution method of bearing capacity based on stiffness ratio is proposed for the first time. And some models of combined strutted structure are calculated on 3-D FEM. The results are analyzed deeply. Some problems occurring in practical projects are explained. Bearing capacity and deformation behavior of combined strutted structure are analyzed in the same time. The influence factors of bearing capacity and deformation behavior of combined strutted structure are make an exhaustive study. Some corresponding conclusions are reached.
