STUDY ON EFFECT OF LIQUEFACTION COUNTERMEASURES FOR UTILITY POLE BY SHAKING TABLE EXPERIMENT

Abstract

 We examine a based pole method to give a gravel drain (the rubble backfill method of construction of the root case part) as measures to subsidence and the slant damage of the utility pole by liquefaction, and inspected the effect by a model experiment, in this study. We clarified that small construction method to take in the root case part of the pole have an effect on to delay the liquefaction around the pole or to control subsidence and aslant by the ground support power in crease.
