TL;DR: In this paper, a 6.0m reinforced soil retaining wall was monitored for two years during and post construction, and the results showed that the lime-treated soil carried the majority of the gravity load but the geogrid reinforcements also contributed to the integrity of the embankment.

TL;DR: In this paper, a procedure for assessing the required long-term strength of the reinforcement while considering its limited length is introduced. But, often there are constraints on such space; e.g., bedrock formation located at a small distance behind the facing.

TL;DR: In this article, an analytical solution is presented to predict deformation behaviors of geotextile-encased stone columns at any depth below the top plane of the columns, based on the unit-cell concept.
Abstract: Based on the unit-cell concept, analytical solutions are presented to predict deformation behaviors of geotextile-encased stone columns at any depth below the top plane of the columns. Under vertical loads at the tops of the stone columns, an axial compression deformation occurs that is often accompanied by a lateral expansion near the top. This deformation characteristic of stone columns was incorporated directly into the proposed analytical method. The shear stress between the encased stone column and the surrounding soil in the vertical direction also was taken into account. In this method, the confining pressure provided by the soil was analyzed based on an analogy with passive earth pressure. The method was verified via comparison with two other analytical solutions. Parametric studies were conducted to investigate the effects of geotextile encasement, vertical applied stress, and column spacing and diameter on the deformation behaviors of columns. The results indicated that geotextile encase...

TL;DR: In this paper, a series of finite difference analyses have been carried out with the Fast Lagrangian Analysis of Continua code (FLAC) to estimate the passive and active earth pressure coefficients, for various mechanical and geometrical configurations of backfill retained by a vertical rigid wall.

TL;DR: In this article, a two-dimensional numerical simulation based on the fictitious stress method (FSM) is also developed to study the mechanical behavior of a twin-tunnel of circular cross section in multi-layered formations by considering the continuity equation for stress and displacement at the interface.
