Integration of continuous seismic profiling in geotechnical investigations off the Belgian coast in Papers.
A comprehensive geotechnical survey for the offshore extention of Zeebrugge harbour illustrates some possibilities and limitations of seismic profiling in Belgian offshore areas and proves a striking example of its successful integration
This paper reports the results of research undertaken to examine some of the important changes that occur in the geotechnical properties of argillaceous sediments with a well developed, pervasive fabric, under tropical weathering conditions
of the geotechnical response of the sediments to weathering.
Priorities for urban expansion within the PWV metropolitan region : the primacy of geotechnical constraints
Applied geology ; Classification ; Dolostone ; Geotechnics ; Housing ; Johannesburg ; South Africa ; Transvaal ; Urban construction ; Urban development ; Witwatersrand
The provision of low cost housing is one of the most urgent problems facing the development of the Pretoria-Witwatersrand-Vaal Triangle metropolitan complex. Geotechnical problems, notably the presence of dolomite must be taken into account when
A new model to analyse the impact of woody riparian vegetation on the geotechnical stability of riverbanks
Bank erosion ; Canada ; Geotechnics ; Impact ; Model ; Ontario ; Riparian vegetation ; Stream ; Tree
The AA. present a geotechnical stability analysis for the planar failure of riverbanks, which incorporates the effects of root reinforcement and surcharge for mature stands of woody riparian vegetation. The analysis relies on a new method
A review of the influence of freeze-thaw cycles on soil geotechnical properties
Canada ; Cold area ; Freeze-thaw cycle ; Geotechnics ; Periglacial features ; Permafrost ; Quebec ; Soil properties
Freeze-thaw cycling affects the geotechnical properties of soils and must be taken into account when selecting soil parameters for stability and deformation analysis of slopes, embankments and cuts in cold regions, especially those underlain
Some geotechnical properties of clayey soils of weathered serpentinite
Clay mineral ; Geotechnics ; Honshu ; Japan ; Mass movement ; Slope ; Slope dynamics ; Soil properties ; Weathering
As a first step towards clarifying weathering, strength, and slope instability relations on slopes made of serpentinite, some geotechnical properties of weathered soil derived from serpentinite in the Oe-yama and Seki-no-miya districts of central
An analysis of mechanisms of ice-wedge casting based on geotechnical centrifuge simulations
Experimentation ; Geotechnics ; Ice wedge ; Model ; Periglacial features ; Permafrost ; Quaternary
The AA. interpret the outcomes of scaled geotechnical centrifuge simulation of ice-wedge casting in terms of the likely significance of Quaternary ice-wedge pseudomorphs observed within different host sediments. In the 6 experiments reported
Australia ; Bank erosion ; Geotechnics ; Mass movement ; Model ; New South Wales ; Riparian vegetation ; Stream
Plants interact with and modify the processes of riverbank erosion by altering bank hydrology, flow hydraulics and bank geotechnical properties. The physically based slope stability model GWEDGEM was used to assess how changes in bank geotechnical
The hydrogeological and geotechnical parameters as agents for gully-type erosion in the rain-forest belt of Nigeria
strongly lie in the hydrogeological and geotechnical properties of a complex aquifer system. These properties are related to the high hydrostatic pressures in aquifers that reduce the effective stress of inconsolidated coarse sands, thereby leading
Geotechnical properties of rock masses : their control on slope form and mechanisms of change along the Napier Range, Western Australia
Australia ; Earth surface processes ; Geotechnics ; Lithology ; Slope ; Slope dynamics ; Western Australia
The results presented here highlight the importance of synthesising standard geomorphological site investigation techniques with quantifiable rock geotechnical parameters, in order to understand slope form and development. Field research has been
This paper presents preliminary results from a study, based on 34 debris flow basins in the southern Coast Mountains of British Columbia, in which the AA. use both morphometric and geotechnical variables to characterize the intensity of the supply
Geotechnical model for great plains hummocky moraine formed by till deformation below stagnant ice

by clay-rich till. In this paper, the AA. test the postulated subglacial origin of hummocky moraine using a geotechnical model of a deforming soil (till). The model confirms that hummocky topography can be the result of failure and deformation of fine
By using glaciological and geotechnical theory, the AA. show that the expression of these deformational styles in East Anglia is a natural response to the stress fields imposed by the ice-sheet, and that in consequence their spatial relationships
are explicable. The depth of deformation is related to the geotechnical properties of till and substrate, the stress and effective stress fields, and found to be consistent with observations.

This review focuses on recent Canadian contributions to hillslope geomorphology, and emphasizes geotechnical studies of mass movement phenomena in the Canadian Cordillera, including debris flows, rock avalanches, talus slopes, rock creep, and slow
earthflow. A brief discussion is included of quick-clay flow slides in eastern Canada, and gelifluction phenomena in arctic and alpine areas. Comparisons are made with similar geotechnical work conducted in the Pacific-rim steeplands.
