چکیده مقاله:

Soil stabilization Were introduced for enhancing engineering properties of soil, including the hydraulic conductivity, compressibility, strength, and density. Methods related to soil stabilization can be categorized in numerous ways, including surcharge load, vibration, enhancing support for structures at hand with structure fill, grouting, and other techniques. Many techniques can be used for different purposes by enhancing some aspects of soil behavior . Ground treatment can enhance the bearing competence of the target soil, reduce the possibility of complete and disparity-based settlement, reduce the possibility of liquefaction with hydraulic fills or saturated fine sand, and reduce the hydraulic conductivity, water retention, and water release of the soil . Nanoparticles can occur naturally or be synthesized from a variety of different materials and functionalized through surface modifications for various applications. Nanoparticles are typically in the scale of 1-100 nm, giving them a large surface area in addition to possessing unique mechanical, thermal, electronic, optical, magnetic, and chemical properties. recentley , for the soil stabilization, more than traditional methods, nanosize material also used with regard to in one of the problems the stabilization soils for large projects, especially in the construction, is problematic soil clay, hence nano technology can also be used as a polymer nano-materials changed engineering characteristics of the soil . Nanotechnology revolves around the creation of a varied collection of nanomaterials (NM), including nanoparticles (NP) along with nano objects. NM is known to be 100 nm lower in terms of dimensions whereas nano objects fall two dimensions lower. An example of this phenomenon can be observed through carbon nanotubes. Nanoparticles are described as materials three dimensions lower than 100 nm. This paper reviews the application of nanotechnology in geotechnical engineering. It discusses soil stabilization and its types, as well as the nanomaterial additives used in soil improvement, and analyzes its effects on soil. Furthermore, this work also discusses the influence of recent advances in nano-instruments and electron microscopes as well as their application in geotechnical studies. The use of nanotechnology has recently gained momentum in the oil and gas industry for its potential applications in enhanced oil recovery (EOR) and as nanosensors in hydrocarbon reservoirs .Understanding of the transport of engineered nanoparticles in wellbores and hydrocarbon formations is necessary for successful application in the field. The mobility of engineered nanoparticles in natural formations is greatly influenced by the mineral and clay composition of the formation and by the dispersion stability of the nanoparticles. Subsurface environments typically vary over a wide range in regard to differences in electrolyte type and concentration, temperature, pH, and mineral composition This paper reviews the use of NM for soil stabilization.
