table test. Fig. 11 shows the three tests: (1) without reinforcement of either the
dam or foundations [Case (a)]; (2) reinforcement of only the dam with continuous
fibers [Case (b)]; and (3) reinforcement for the dam with continuous fibers and the
foundations with model sheet piles [Case (c)].
An outline of the model and the arrangement of instruments are shown in
Fig. 10. The foundations were made by depositing wet material in the shaking
box with 30-cm-deep water. The dam was also constructed by placing formwork
and depositing wet material in the forms filled with water like the foundations.
The relative density was about 50%. The reinforcement of the dam in Case (b)
consisted of two fibers from a four-hole nozzle bundled into eight fibers, which
were pushed out by high-pressure water and mixed with sand injected through a
hose via a hopper. The reinforced parts were compacted with a small vibrator,
and the continuous fibers comprised 0.2% of the dry weight of the sand. In Case
(e), a sheet pile model of 15-cm-thick acrylic plate was installed placed from the
top of the dam wall to the base of the foundations in Case (b).
