EVALUATION OF FULL SCALE EMBANKMENT WITH HEXAGONAL WIRE MESH REINFORCEMENT WITH ADDITIONAL SURCHARGE

A fully instrumented test embankment reinforced with hexagonal wire mesh was constructed on soft clay foundation in Thailand. The reinforced wall consisted of 90 degrees inclined gabion facing on one side and a sloping unreinforced sandfill in the opposite side with a total height of 6.0 meters. The existing embankment was later raised up to another 1.0 m. The maximum observed settlement and lateral movement due to additional surcharge was 0.049 m at 190 days and 0.007 m at 173 days, respectively. The excess pore pressure increased due to additional surcharge and gradually dissipated. The predicted settlement by using Cv from Asaoka's method presents a higher rate of settlement than by using Cv from oedometer test. The calculated settlement by Asaoka's method is closer to the observed settlement. The maximum tension lines in the test embankment were closer to the tie-back wedge assumption. The tension induced in the hexagonal wire mesh in the laboratory during pullout test was higher than the monitored data from the full scale embankment wherein the tension induced in the zinc-coated hexagonal wire mesh was slightly higher than the PVC-coated. The forces developed in the reinforcement of full scale embankment was in the working stress level where the corresponding laboratory pullout tension and displacement of reinforcement in the field were correlated. The external stability of the test embankment has been verified to be safe. (A)
