A three-dimensional rotational failure mechanism for earth slope is extended from toe to include face and base failure. An efficient optimisation method simultaneously employed find the least upper bounds critical height in order avoid missing global minimum. Compared with results analysis based on alone, best estimates of are obtained. The calculated given form graphs tables a wide range parameters. surfaces also investigated assess influences geometrical constraint soil property mechanism.
A three-dimensional (3D) kinematically admissible rotational failure mechanism is extended from toe to include face and base for homogeneous slopes in both purely cohesive frictional/cohesive soils. In the strict framework of limit analysis, an analytical approach derived obtain upper bounds on slope stability corresponding type critical mechanism. Compared with available results finite-element limit-analysis method, 3D mechanisms give best estimate bound. set charts presented a wide range...
Basement excavation inevitably causes stress changes in the ground, leading to soil movements that may affect serviceability and safety of adjacent tunnels. Despite paying much attention basement–tunnel interaction, previous research has mainly focused on influence tunnel location relation basement, stiffness, geometry. The effects sand density basement wall stiffness nearby tunnels due excavation, however, have so far been neglected. A series three-dimensional centrifuge tests were thus...
The traditional approaches for evaluating the stability of slopes or earth dams subjected to water drawdown are performed under plane-strain two-dimensional (2D) condition. Three-dimensional (3D) effect is neglected in assessment safety a slope limited by rigid structures dam constrained narrow valley. Based on kinematic approach limit analysis, 3D rotational failure mechanism adopted here investigate influence slopes. Several charts presented conveniently estimate factor four different...
Many constitutive models are available nowadays to predict soil–structure interaction problems. It is sometimes not very easy for engineers select a suitable soil model carry out their design analyses in terms of complexity versus accuracy. This paper describes the application three back-analyse well-instrumented centrifuge test, which effect basement excavation on an existing tunnel was simulated. These include linear elastic – perfectly plastic with Mohr–Coulomb failure criterion (called...
Humic acid (HA) enhances colloidal transport in porous media, yet the mechanisms by which HA adsorption conformation affects colloid remain unclear. This study investigated influence of on petroleum-hydrocarbon-contaminated soil colloids (TPHs-SC) saturated sand columns. The presence TPHs surface occupied sites, hindering from forming a horizontal conformation, as observed uncontaminated (SC). Instead, vertical was formed, reducing overall HA. Vertically adsorbed increased diffuse...
Various analytical solutions have been proposed for a unit-cell consolidation with vertical drain under surcharge loading. These involve different assumptions to address various aspects of consolidation. There is lack generalised solution analysing soil assisted by loading conditions. This paper presents simplified multi-ramp Generalised governing equations equal-strain are solved. Simultaneous radial and flow conditions, as well the combined effects resistance smear, taken into account...
