Role of unsaturated soil mechanics in geotechnical engineering

Transient seepage model for saturated-unsaturated soil systems: a geotechnical engineering approach

A two-dimensional finite element model is proposed to simulate transient seepage for complex groundwater flow systems. The complete soil system is treated as a continuum encompassing flow in both saturated and unsaturated zones. In the unsaturated zone, the air phase is assumed to be continuous and open to atmospheric pressure. The coefficient of permeability of the unsaturated soil is assumed ...

Biological Considerations in Geotechnical Engineering

The understanding of soil behavior during the last 300 years has centered on mechanical principles, geological processes, and later on, mineralogy and the relevance of colloidal chemistry. More recently, research in biology and earth science has enabled important advances in understanding the crucial involvement of microorganisms in the evolution of the earth, their ubiquitous presence in near ...

The Role of Micro-Mechanics in Soil Mechanics

Desktop GIS for Geotechnical Engineering

A desktop Geographic Information Systems (GIS) for Geotechnical Information Management system has recently been developed to assist geo-technical managers, planners through flexible application with all common desktop GIS functionalities and customized tools like Borehole Viewer and Stripchart to relate alignments and cross-sections to a specific location and/or region on the map, and create th...

role of cultural iran in promotion of multilaieralism in central asia and caucasus

cultural iran is a scope that is more extended than the political territories of iran as a political unit. this concept means that cultural geography(mehdi moghanlo-1383-1) of iran is greater than its political geography which, according to history, has a long history extending west-east from kandahar to the euphrates and north-south from the persian gulf to the caucasus including transoxiana a...
