In practical engineering, the total vertical stress in soil layer is not constant due to diffusion, and varies with time depth. Therefore, purpose of this paper investigate effect diffusion on two-dimensional (2D) plane strain consolidation properties unsaturated soils when A series semi-analytical solutions terms excess pore air water pressures settlement for 2D can be derived joint use Laplace transform Fourier sine expansion. Then, inverse solution given domain using a self-programmed...
Abstract Due to the phenomenon of stress decay in space, total vertical varies with depth layered soil stratum. The physical properties unsaturated stratum and nonuniformity external load direction pose significant effects upon consolidation process, while related works have viewed modest development at present. Therefore, main objective this study is explore one‐dimensional (1D) patterns multilayered ground considering depth‐dependent by a semi‐analytical procedure. According 1D theory...
This paper presents semianalytical solutions of one-dimensional (1D) consolidation for unsaturated soils with depth-dependent vertical stress induced by multistage load. Based on the 1D theory proposed Fredlund and Hasan, excess pore pressures settlement subjected to in a Laplace domain are derived adopting transform differential operator method. Then, analytical time obtained Crump’s method, corresponding computing programs compiled. The correctness has been validated comparing current this...
Since the wide applicability of axisymmetric consolidation model, problem unsaturated soils has gradually become a hot issue. However, mixed boundary conditions free strain have not been fully considered. The condition is main factor affecting process with determined model and related parameters. In this paper, governing equations water air in polar coordinate were given according to two stress state variables theory soils, Darcy’s law, Fick’s law under condition. Based on hypothesis, series...
The backfill construction of a utility tunnel is as important its main structure construction. While the existing research on tunnels focuses structure, rare attention has been paid to In this paper, with practical comprehensive project background, variety different schemes were designed, and corresponding numerical simulations performed finite element analysis software Midas. influence side wall, roof, floor was systematically studied analyzed, displacement stress variation curves in...
This paper studies the one‐dimensional (1D) consolidation behavior for unsaturated stratum subjected to piecewise cyclic loading. Combined with widely accepted theory of soils, a semianalytical method was employed investigate foundation considering loading in Laplace domain. Furthermore, reduced solutions were produced perform verification work accompanied by results existing literature. Finally, case study conducted explore characteristics under (i.e., triangular and trapezoidal loadings)....
