Modeling and Analysis of Risk Factors on Soil Anchoring

Given the limited scale of development and urbanization of land in the urban master plan and thenecessity of using underground spaces, Excavation in urban areas is important. inevitably limits theengineers of the excavation with vertical or near vertical walls are built of land in urban areas.Accordingly, the stability of supply, particularly with regard to the applied load excavation fromadjacent structures, civil engineering challenges facing the guard structure is built. One of the waysthat today, especially for urban excavation is common in urban areas deep into the tailoring is back. Inthis paper the method of sewing the back by a excavation software PLAXIS 2D, It is modeled after thesurvey results of two-dimensional model, the effect excavation anchorage length, the mechanicalparameters of soil (soil internal friction angle, modulus of elasticity of soil) has been investigated. Theresults of artificial neural network is seeking to determine the success of the guard wall is moving. Forthis purpose, the artificial neural network application software MATLAB was used. Two-dimensionalnumerical model of the wall (beam guard) wall with Germany, the German non-tangly inhibitionanchor node to node, the tangly inhibition Germany GEOGRID and the soil is simulated by the modelsoil cured. Complete Excavation involves excavation to a depth of 2 to 3 meters, which is usuallyconsidered to be Find the anchorage in the sump pit dug in the structure and stress in the inhibition offorce is also modeling.
