• Abstract:
  A research implementation project was undertaken to demonstrate the use of an innovative technology known as "in-situ soil vitrification" for slope stabilization purposes. The equipment needed to accomplish vitrification in the field, called SOVIT, was developed at Texas Tech University as part of a previous TxDOT sponsored research project. Three sites with a history of frequent slope failure were selected for stabilization. The first of these was on the approach embankment to Motley Drive overpass over I-30 in Dallas District. The most critical failure surface was identified through analysis and a row of eleven vitrified piers, each 3 ft deep, was installed at 6-ft spacing to intercept the failure surface. The second slope was a highway cut on the south side SH-36 near Hamilton, Waco District. At this site, slope movement had occurred at the interface between the near-surface weathered material and the un-weathered material found at depths below 2 ft. Since the failure area was not accessible from the road level, a temporary access road was cut parallel to the slope. A row of sixteen vitrified piers was installed to a depth of 3-4 ft. The center-to-center spacing between piers was 6 ft. The third site in Tyler had to be abandoned due to unfavorable weather.
