Embankment Settlement Calculation Based on the Unsaturated Soils Theory

Abstract:

Based on the one-dimensional constitutive relationship of unsaturated soils, this thesis has established the calculation model for embankment settlement with lateral deformation and without lateral deformation in accordance with the mechanic characteristics and in consideration of the influence of water environment. In addition, the thesis has provided the calculation methods for embankment settlement under various working situations (like under the situations of external load function, self-weight effect, increasing of the groundwater level, the invasion effect of rain water and the comprehensive effect of various working conditions) and used the settlement deformation results from the experiments of embankment models to check the calculation method. The method put forward in this thesis could not only be used in the calculation of the settlement deformation under load, but also could be used for the calculation of the deformation caused by the changes of water content in the embankment.
