In geotechnical engineering, a tieback is a structural element installed in soil or rock to transfer applied tensile load into the ground. Typically in the form of a horizontal wire or rod, or a helical anchor, a tieback is commonly used along with other retaining systems (e.g. soldier piles , sheet piles, secant and tangent walls) to provide ...
A knee wall is a short wall, typically under three feet (one metre) in height, used to support the rafters in timber roof construction. In his book A Visual Dictionary of Architecture , Francis D. K. Ching defines a knee wall as "a short wall supporting rafters at some intermediate position along their length."
The first geosynthetic-reinforced soil walls were built in France in 1970 and 1971. [5] Geosynthetic-reinforced walls have been in use in the United States since 1974. Bell and Steward (1977) describe some of these early applications, which were primarily geotextile wrapped-face walls supporting logging roads in the northwestern United States.
The walls must resist the lateral pressures generated by loose soils or, in some cases, water pressures. [3] Every retaining wall supports a "wedge" of soil. The wedge is defined as the soil which extends beyond the failure plane of the soil type present at the wall site, and can be calculated once the soil friction angle is known. As the ...
MSE walls combine a concrete leveling pad, wall facing panels, coping, soil reinforcement and select backfill. [79] A variety of designs of wall facing panels may be used. [79] After the leveling pad has been laid and the first row of panels has been placed and braced, the first layer of earth backfill is brought in behind the wall and compacted.
The first modern theoretical models for soil consolidation were proposed in the 1920s by Terzaghi and Fillunger, according to two substantially different approaches. [1] The former was based on diffusion equations in eulerian notation, whereas the latter considered the local Newton’s law for both liquid and solid phases, in which main variables, such as partial pressure, porosity, local ...
The maximum rate at that water can enter soil in a given condition is the infiltration capacity. If the arrival of the water at the soil surface is less than the infiltration capacity, it is sometimes analyzed using hydrology transport models, mathematical models that consider infiltration, runoff, and channel flow to predict river flow rates ...
As viewed by the Natural Resources Conservation Service, soil drainage is the number one priority for location of certain grasses. Poorer drainage causes less infiltration of water into the soil as groundwater recharge causing ponding and flooding of surrounding crops. Higher drainage becomes more droughty which hinders the establishment of ...
