This study uses laboratory experiment to clarify the failure mechanism of granular soil slopes when subjected to high rainfall intensity. A rainfall simulator was employed to perform tests on slopes with convex and concave profiles; the slopes were non- homogeneous ...

<p>Mechanically stabilized earth (MSE) walls reinforced by geogrids and geotextiles have seen a tremendous growth over the past thirty years. However, along with this growth has come numerous failures consisting of excessive deformation and, in some cases, ...

We first review, in five sections, the external perturbations and their associated processes which can lead to landslide failure: i) increase of slope angle, ii) increase of load applied to the slope, iii) rise of groundwater level and pore pressure, iv) frost ...

This paper describes random finite element analyses of anisotropic 2-D undrained clay slopes with randomly distributed shear strength. The analyses take into account the rotational orientation of the principle axes of anisotropy that might be observed in natural ...

<p>Many soil stability problems in geotechnical engineering can be analyzed by means of the classical slip line method - a relatively rigorous (baseline) solution. A slip line solution satisfies the lower bound theorem in plasticity theory, ie it satisfies ...

Excavated slopes in open pit coal mines are designed to be as steep as possible consistent with stability and safety requirements. Slope failures occur for many reasons, including oversteepening. This paper is concerned with slope design and excavation experience ...

In order to enhance the detection of prospective rock falls in calcareous cliffs, 25 rock falls have been described in a more detailed way than for an inventory. They are representative of middle size rock falls (10 to 100,000 m3) occurring in the French Subalpine ...

The Folkestone Warren and adjacent sea cliffs have provided considerable challenges to students and practitioners in both engineering and geology since the decision was taken in the 1840's to use this route for the main line between Folkestone and Dover, Kent. ...

Evaluating the reliability of slopes against sliding failure is complicated by the fact that most slope soils are spatially variable. This means that instead of nice circular failure surfaces, slope failures tend to be more complex, following the weakest path ...

The behavior of mechanically stabilized earth walls with modular block facing and geosynthetic reinforcement was investigated with numerical models that simulate construction of the wall.
