Outline of Annual Research Achievements

Active and passive limits in sand heaps provide a fundamental knowledge on arch action under two extreme conditions. In the present study, the lower bound limits of an infinite wedge were analyzed using the Newton method. To validate the results, a series of 1G physical models of an embankment inclined at angle of repose was conducted. Dry silica sand no.6 was used to build the embankment by pouring from the sieve source. Four tests were conducted with different conditions of maximum settlement and hysteretic reversals. Yielding in the embankment was induced by the settlement and uplift of the stiff base physically hinged together at the center. As the basal deflection was slightly increased, the central pressure significantly decreased. Once the base was upturned, the central pressure gradually increased. Though hysteretic reversals were applied in the experiments, active and passive limits were reasonably consistent with measurements in a certain range of deformation.
