LIQUIDIZIN MODEL SHAKING TABLE TEST OF AN EXISTING FOUNDATION REINFORCED WITH MICROPILES
|
´˜^i‰pjF |
Seismic retrofit of existing foundations is subject to construction restrictions such as overhead clearance and neighboring structures, so no conventional methods can hardly been applied in an increasing number of cases. Small-diameter pipe piles that can be constructed in narrow space have recently been gathering attention. A full study, however, needs to be made of their behavior during an earthquake. In this study, a model test was carried out using a vibrating table to qualitatively identify the dynamic behavior of a pile foundation reinforced by small-diameter pipe piles and the effect of reinforcing the foundation.
