Search Tips. Phrase Searching You can use double quotes to search for a series of words in a particular order. For example, "World war II" (with quotes) will give more precise results than World war II (without quotes). Wildcard Searching If you want to search for multiple variations of a word, you can substitute a special symbol (called a "wildcard") for one or more letters.
Proceedings of GeoCongress , held in Oakland, California, March , Sponsored by the Geo-Institute of ASCE. This collection contains peer-reviewed papers integrating current geotechnical research and practice. Papers explore recent advances, sustainability, the use of new technologies, and cast histories. Under field conditions, measurements of color are reproducible by different individuals within units of hue (one Munsell soil-color chart) and 1 unit of value and chroma. Notations are made to match the chips included on the color charts, typically the nearest whole unit of value and chroma.
However, soil tests need to be preformed to determine the buoyant weight of the soil. It is conservative to use the full density of the soil in conjunction with water. Figure illustrates the application of the loads. Figure a illustrates the expected distribution for a uniform soil without water present. of the behavior of slopes with cohesionless materials under large seismic shakings. Small size sandy slopes were used for static inclination tests, sinusoidal shaking tests, and seismic shaking tests. Duration of sinusoidal shakings was long enough to terminate the slope failure.

static and dynamic stability of earth slopes, natural slopes, cut slopes, embankments, landslides, etc. These slopes can be formed out of soil or rock. Limit equilibrium method and slices-based method, which are more traditional methods, are used in the analysis in the stability og soil slopes under seismic loading.
These methods have their ownFile Size: KB. This study represents an initial part of a comprehensive investigation of slope behavior in cemented soils, and it is directed toward: (1) documenting of the behavior of natural slopes in weakly cemented soils, (2) defining the engineering response of weakly cemented soils under static and dynamic loading, (3) establishing the stress conditions.
The stability of slopes and embankments under the influence of static and seismic loads has been the subject of study for many researchers. This paper presents the mechanisms and causes of landslides as well as the forms of failure of slopes and embankments under static and seismic loading, with examples of failures from both GreekAuthor: Nicolaos Alamanis.

To study the effect of reinforcement type and quantity on the response of model slopes in this study, a series of shaking table tests were carried out on model slopes reinforced with different quantities of geotextile and geogrid. Model slopes were constructed to an angle of 45° using poorly graded sand.
Acceleration of base shaking and shaking frequency were varied in different by: 8.

The static and dynamic stability analysis is based on the assumption of plane strain condition; the potential failure surface and the slope safety factor, both for static and seismic conditions, are evaluated considering for the soil a plastic behaviour and the Mohr-Coulomb failure by: 3. Introduction.
Performance of soil slopes under seismic conditions is an important aspect to consider in designing these slopes. Though the knowledge regarding stability analyses and monitoring the slope movement and also the stabilization techniques improved substantially in recent years, instabilities of natural and manmade soil slopes pose danger in several regions especially during Cited by: The soil mechanical model must allow representing the correct behavior of soil under the structure static loads accounting for the interaction effects due to neighboring buildings.
