GE-97-14 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Engineering, School of Civil Engineering Thesis (M.Eng.) - Asian Institute of Technology The mechanism governing soil reinforcement interaction has been simplified into two: soil sliding along the interface and pullout of reinforcement from the soil. The pullout tests have been commonly used for the investigation of pullout mechanism. To formulate the pullout resistance, pullout tests were conducted on hexagonal wire mesh embedded in silty sand locally known as Ayutthaya sand. Two types of wire mesh were tested, one is galvanized having a small aperture with dimension of 80 mm x 60 mm while the other is galvanized with additional PVC sleeve having larger aperture with dimension of 100 mm x 80 mm. The tests were conducted under normal pressure ranging from 3.50 to 9.10 t/m2 and pulled at a rate of Imm/min. In addition, the test results from previous investigators related to this study were also used. The results from this study revealed that the failure mechanism of both types of the reinforcement are different depending on the cell size aperture, reinforcement stiffness, reinforcement material, fill material, and vertical normal stress. The total pullout resistance of hexagonal wire mesh reinforcement contains two components, namely: friction and bearing resistance. The bearing resistance is higher than the friction resistance for both types of reinforcement. The applied normal pressure has an influence on both the bearing and friction resistance. The higher the normal pressure, the higher the friction and bearing resistance. Besides, the friction and bearing resistance mobilized on the galvanized wire mesh is greater than the PVC-coated wire mesh due to greater number of longitudinal and transverse member. The proposed analytical method of predicting the pullout-displacement relationship agreed with the test results reasonably well.
