Simulation Analysis for the Engineering of Soft Soil Foundation on the Based of ADINA

Abstract

It is important geotechnical problem to consolidation of soft soil foundation. Three-dimensional finite element model is established on the based of Biot consolidation theory, the model is loaded and calculated on the based of considering lateral deformation and spatial seepage, elastic-plasticity character of soil, construction stage loading progress etc. case study is analyzed to obtain the regular of settlement, lateral displacement and excess hydrostatic pore pressure. The calculation value of finite element method is reasonable to compare with measured data. The finite element method is used to simulate truly every position and step settlement, later displacement and excess hydrostatic pore pressure, feedback calculation value can instruct information construction, control and adjust fill rate of construction, and then settlement of embankment is controlled better. The method can forecast final settlement of embankment more exactly to supply reference of design and construction.
