Shear sieveing in do Ground - prove Exampleotechnicians and construction firms to determine the usability of do Ground through the estimation of its strength and necessary properties (Bouazza et al., 1997). Made ground can be easily found all around us they could be in the form of sandy, silt, clay and loamy soil (Bouazza et al., 1997). Shear Testing is a standardized laboratory analyse that has been used to detect the mechanical properties of Made ground, most especially its tensile strength (Woodward, 2005). Such a test is helpful in determining the usability of the ground and outlining the soils harmful contents that may make construction works on the ground impossible. In this case, serious consideration is given to the environmental impact of soil properties how does the environment is affected by the constituents of a soil? Are there close to harmful objects in the soil, for instance in brownfield and other abandoned property? (Geltman, 2000).Shear Testing of Made Groun d can be simply carried out by using the Direct Shear Test (Das, 2008). Information about the standard reference, test expectations, equipment, test procedures, test data and analysis are provided as followsBeing the commonest method of discovering the tensile strength of soils, Direct Shear Test could help to estimate the weight down of internal friction (Hillel, 1998). When plotting the shear stress against the horizontal displacement, the maximum, shear stress can be obtained. Therefore, later carrying out several just-confining stresses, it is possible to plot the maximum shear stress against the vertical confining stresses for distributively of the tests produced. Then a straight-line approximation of Mohr-Coulomb failure envelope curve could be drawn (Parry, 1995). And the shear strength of the soils under investigation could be estimated using the formula belowix. I started the motor with chosen run so that the rate of shearing is at a selected constant rate, and take th e horizontal displacement gauge, vertical displacement gauge
