Strengthening and Retrofitting shear strength of clay soils in conduits by polymer materials

In order to discussing the positive effect of polymer materials on shear strength of reinforced clay in conduits , shear tests achieve on reinforced clay in soil mechanics laboratory. In this research study , by utilizing polymer materials (geotextiles ) in a specified clay and performing uniaxial shear test on reinforced soil , it is distinguished , by setting geotextile sheets in alignment of 60 degrees to failure plane, the maximum increase in shear strength ( about 25 % ) may be obtained.
