Example text

For each test section, four displacement potentiometers and two LVDTs were used to measure settlements of the sill. Six displacement potentiometers were used to measure lateral movement of the abutment wall. In addition, six potentiometers and six LVDTs were used to measure lateral movements of the two wing walls. Three-dimensional movement of the abutment wall and one of the wing walls for each test section were traced by using a laser displacement measurement device. A total of 74 high-elongation strain gauges (MicroMeasurement Type EP-08-250BG-120) were mounted on five sheets of Amoco 2044 geotextile for the Amoco test section Legend Potentiometer LVDT LVDT Potentiometer Strain gauge Contact pressure cell 24 Layer E Layer J Layer D Layer I 22 20 22 18 16 20 18 Layer C Layer H 16 14 12 24 14 Layer B Layer G 10 12 10 8 8 Layer A Layer F 6 6 4 4 2 2 Concrete Foundation Instrumentation Layout of GRS Abutments Figure 2-16.

The test abutments were constructed over a rigid floor. 9 m thick. 2 m in all layers. A concrete “cinder” block of dimensions 194 mm by 194 mm by 397 mm and with a split-face was used as a facing element.

A polypropylene needle-punched nonwoven geotextile, with tear strength = 16 kN/m, grab strength = 1,200 N, and elongation at failure = 80 percent, as determined with DIN 53815 (German Standards: testing of textiles) was used as reinforcement. 35 m. Wrapped facing was adopted for the structure. 8 m in diameter were used to load the GRS embankment, which produced a total load of 510 kN or 130 kN/m2.
