2 DEVELOPMENT, INSTRUMENTATION, AND
CONSTRUCTION OF FULL-SCALE TEST WALL

Figures 1 and 2 show the front and side views of the RS wall with the
instrumentation plan. The RS wall rests against a reinforced concrete structure
without any connection. It has one vertical face along side with one of the sides of
the reinforced concrete shelter and another side sloping down from the top of the
reinforced concrete structure. As a result, the vertical face of the RS wall has a
triangular shape with a height of 3m and base width of 5.8m. The length of the
wall in the slope direction was 4.5m. A reinforced concrete slab 0.8m thick was
to be placed on the sloping side of the RS wall. Both facing and reinforcement for
the RS wall were geotextile-type PEC200 (Polyfelt). PEC200 is composite
geotextile, which has woven high-strength polyester (PET) yarns on a
mechanically bonded polypropylene (PP) nonwoven base. The technical
specification of the geotextile PEC200 is shown in Table 1 . The polyester
yarns provide the required strength and the polypropylene base is the geotextile
layer providing for filtration, drainage, and separation function. This type of
geotextile was chosen for this project mainly because it has a very high strength
and is suitable for reinforcement in poorly draining soil, typical of local tropical
residual soils.
The front and side views of the reinforced earth wall are shown in Figs. 3
and 4. The height of the front face of the RE wall is 3.75m, and the width of
