PULLOUT AND DIRECT SHEAR RESISTANCE OF HEXAGONAL WIRE MESH ENFORCEMENT IN WEATHERED BANGKOK CLAY

Pullout and large scale direct shear tests were conducted on two types of hexagonal wire mesh: zinc-coated and PVC-coated, embedded in weathered Bangkok clay. To investigate the interaction between reinforcement and soil, and to determine the pullout and shear resistance of each type of reinforcement, tests were conducted at normal pressures: 30, 50, 70, and 90 kPa and pulled or sheared at a rate of 1 mm/min with effective lengths equal to 0.70, 0.90 and 1.10 m. In-air tensile tests were also conducted to investigate the relationship between tensile strength and in-air length. The maximum pullout load capacity of zinc-coated and PVC-coated hexagonal wire mesh are 72.0 kN/m and 60.4 kN/m, respectively, with the higher capacity of the former attributed to its higher stiffness than the latter. Nonlinear distribution of displacements, strain and tension were observed with mobilized wire mesh tension directly proportional to the applied normal stress. The direct sliding coefficient obtained for both types of hexagonal wire mesh was 1.07. (A)
