STUDY ON SETTLEMENT ASSOCIATED WITH LIQUEFACTION OF SAND SUBJECTED TO IMPACT LOADS

Abstract

quakes resulted in severe damage to engineering works. Extensive laboratory investigations1)-10) on this liquefaction phenomenon have been conducted by many soil engineers for many years, especially since the Niigata earthquake of 1964 which provided much valuable information of this phenomenon. Some important conclusions have been obtained, on the necessary combination of soil conditions and vibratory deformations leading to liquefaction and on the liquefaction process, from these studies. Unfortunately only a few attempts, however, seem to have been made to study this phenomenon in a quantitative way. Ref. 9) may be one of such works of solving case problem in Niigata. The present
