| Abstract: |
| Using a semi-analytical method,this paper studies steady-state responses of an unsaturated elastic half-space foundation under a harmonic load.Based on the dynamic control equation of unsaturated soil and the boundary conditions of the unsaturated elastic half-space,the semi-analytical function of the foundation element is established.By the weighted residual method, this paper gets the unsaturated semi-analytical equation of the steady-state responses on the elastic half space.The semi-analytical equations are solved to obtain the horizontal and vertical displacement amplitudes of the unsaturated elastic foundation under the vertical harmonic load.The effects of saturation and foundation depth on pore pressure and displacement were calculated numerically.The research results show that the application of this method to study the steady-state response of unsaturated elastic half-space foundations is practical and effective. |
