| Abstract | A fully instrumented test embankment reinforced with hexagonal wire mesh was
constructed on soft Bangkok clay foundation in Thailand. The reinforced wall consisted of
10 degrees inclined gab ion facing on one side and a sloping unreinforced sand fill in the
opposite side with a total height of 6.0 meters. The existing embankment was raised up to
another 1. 0 m. The maximum observed settlement and lateral movement due to the
additional surcharge is 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, while the calculated settlement by
Asaoka' s method is closer to the observed settlement. The calculated settlement by using
Cv from oedometer test demonstrated some difference with respect to the observed
settlement. The maximum tension lines in the test embankment were closer to the tie-back
wedge assumption. The tension induced in hexagonal wire mesh in the laboratory during
pullout test is higher than the monitored data from full scale embankment wherein the
tension induced in zinc-coated hexagonal wire mesh is higher than PVC-coated. The
forces developed reinforcement of full scale embankment is in the working stress level.
The external stability of the test embankment has been verified to safe. Design guidelines
of MSE wall with hexagonal wire mesh reinforcement has been proposed and
demonstrated using the existing hexagonal wire mesh reinforced test embankment. |
