Single helix earth anchors Guyed mast anchor. An earth anchor is a device designed to support structures, most commonly used in geotechnical and construction applications. Also known as a ground anchor, percussion driven earth anchor or mechanical anchor, it may be impact driven into the ground or run in spirally, depending on its design and intended force-resistance characteristics.
This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic ...
Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...
Earth hummocks – Small knoll or mound above ground; Kurum – Mantle of loose rocks moving by creeping on gentle slopes. Lithalsa – Frost-induced raised land form in permafrost areas; Nivation hollow – Geomorphic processes associated with snow patches
Tiebacks to reinforce a slurry wall at Ground Zero, New York. In geotechnical engineering, a tieback is a structural element installed in soil or rock to transfer applied tensile load into the ground.
Technical geography is the branch of geography that involves using, studying, and creating tools to obtain, analyze, interpret, understand, and communicate spatial information. [1] [2] [3] The other branches of geography, most commonly limited to human geography and physical geography, can usually apply the concepts and techniques of technical ...
For example, chalk is made up partly of the microscopic calcium carbonate skeletons of marine plankton, the deposition of which induced chemical processes to deposit further calcium carbonate. Similarly, the formation of coal begins with the deposition of organic material, mainly from plants, in anaerobic conditions.
Typical earthworks include road construction, railway beds, causeways, dams, levees, canals, and berms.Other common earthworks are land grading to reconfigure the topography of a site, or to stabilize slopes.
