Mechanically stabilized earth (MSE or reinforced soil) is soil constructed with artificial reinforcing. It can be used for retaining walls , bridge abutments, seawalls , and dikes . [ 1 ] [ 2 ] Although the basic principles of MSE have been used throughout history, MSE was developed in its current form in the 1960s.
Soil resistance, a related term refers to the ability of soil to resist changes or the extent to which a soil will recover from any cropping or management change. The term is distinct from Soil resilience as resistance is the inherent capacity to withstand disturbance, while resilience is the capacity to recover after disturbance. [1] [2]
Influenced primarily by soil forming processes over time, it commonly forms below an albic horizon. It has less clay content than an argillic horizon but is still a visible layer. [ 3 ] In the pedogenesis process under a chronosequence , once the soil develops into an alfisol, the Cambic horizon will develop into an argillic (Bt) horizon.
A Cellular Confinement System when infilled with compacted soil creates a new composite entity that possesses enhanced mechanical and geotechnical properties. [34] When the soil contained within a CCS is subjected to pressure, as in the case of a load support application, it causes lateral stresses on perimeter cell walls.
Soil stabilization is a general term for any physical, chemical, mechanical, biological, or combined method of changing a natural soil to meet an engineering purpose. [1] Improvements include increasing the weight-bearing capabilities, tensile strength, and overall performance of unstable subsoils , sands, and waste materials in order to ...
Previous stresses and other changes in a soil's history are preserved within the soil's structure. [4] If a soil is loaded beyond this point the soil is unable to sustain the increased load and the structure will break down. [4] This breakdown can cause a number of different things depending on the type of soil and its geologic history.
This broader definition encompasses the overall concept of soil compaction, subsidence, and heave. Some types of soil, mainly those rich in organic matter, show significant creep, whereby the soil changes volume slowly at constant effective stress over a longer time-scale than consolidation due to the diffusion of water. To distinguish between ...
This area, as with many other geosynthetics, is very active, with a number of different products, materials, configurations, etc., making up today's geogrid market. The key feature of all geogrids is that the openings between the adjacent sets of longitudinal and transverse ribs, called “apertures,” are large enough to allow for soil strike ...
