SHAKING TABLE TEST ON REINFORCED SAND

Abstract

Shaking table tests were conducted on saturated sand layer reinforced with wires in order to apply reinforced earth method to liquefaction countermeasure method.
In this paper, the effects of placing direction, reinforcing range and stiffness of reinforced materials on the liquefaction resistance are investigated. Shown below are results of this tests.
i) Reinforcing effect is confirmed on shaking table tests.
ii) If reinforcing effect is greater for vibration at low acceleration ratio than for vibration at high acceleration ratio.
iii) Reinforcing effect is greater as stiffness is greater, reinforcing interval is narrower and reinforcing area is wider.
