BEHAVIOR OF DRY-RETAINING WALL

Abstract

The research objective was to study the behavior of dry-retaining wall bricks. The general
method for constructing the retaining wall used the reinforced concrete structure. This research used
interlocking bricks was an alternatives material from community products. There was a low price and
operated cost and simply can construction by local general workers. The research was to create a model of
the interlocking bricks, retaining wall used size in width x height x thickness to 1.50 x 2.00 x 0.125 m
respectively. Selected distribution horizontal earth pressure by materials was sand, rubber plate, steel
molding, steel plate, hydraulic jack. Rubber plate thickness to 2.00 mm for cover sand in mold to 0.15 m of
radius in a semicircle shape and height 1.60 m thickness 8.0 mm. Used hydraulic jack 30 tons for apply load
circle step by step and measure displacement value by dial gauge. The models had 4 patterns was half and
full bricks wall, reinforced bars in half bricks wall with tight force and reinforced bars in half bricks wall
with tightly force and anchor. The results were found a reinforcement bars with a half arrange interlocking
bricks wall with anchorage pattern shown a maximum stability with an applied force of 10 lb for increasing
the strength of the retaining wall.
