Earth Pressure Cells which are used for the measurement of earth pressures on structures. Earthbag construction uses earth as the primary structural element, and it helps create curvaceous, sensual architecture while providing structural integrity. Earth – Mother Earth, can impose a pressure on a structure and must be allowed for in design. The land must be analyzed to check whether it has the ability to withstand the heavy retaining wall structures. Two points requiring special consideration are analysis for load factors of 1.7 times lateral earth pressure and 1.4 times dead loads and fluid pressures, and provision of splices at the base of the stem, which is a point of maximum moment. Careful design and construction of these structures is essential for safety and longevity. PRetaining structures form an important component of many civil engineering and geotechnical engineering projects. Gravity retaining structure refers to a kind of retaining structure that balances the earth pressure behind the wall mainly on the gravity of the body of wall. Wiegert's computer models suggest that the debris stream has very tiny grains of dust, no more than a few microns wide, and they will be gently pushed toward Earth by the radiation pressure of the sun. In the Flood geological model presented in this paper, the only 'rocks' which can be considered to retain their pre-flood characteristics are those of the inner mantle, and the core, below the 660-km discontinuity. Contrary to belief among some creationists, the structure and composition of the inner earth is inferred with a large degree of confidence.53–68 Progress in the study of seismology (Figure 3) and high-pressure mineral physics now allows soundly based conclusions .. The footing and For environmental engineering structures where these conditions are common, ACI Committee 350 had recommended use of 1.7 for both soil and liquid pressure (see ''Environmental Engineering Concrete Structures,'' ACI 350R).
