Blast Liquefaction Test of Saturated Sand Foundations Disposed by a Drainage Rigid Pile

Drainage rigid piles represent a commonly used antiliquefaction treatment for saturated sand foundations. Small-scale model tests on the liquefaction-resistant characteristics of drainage subjected to blasting were conducted in this study. The effect ordinary and disposal foundations was investigated by using carbon dioxide (CO2) fracturing generate explosive vibratory loads. test results showed that blast vibration load increased relative density site approximately 10% proportional burial depth. vertical acceleration attenuations resulting from two blasts 35% 45%, respectively, variation pattern both sides is similar. can dissipate more than 70% excess pore water pressure under liquefaction quickly accumulate and, likewise, pressure. higher at is, effective pile is. This field provides design reference engineering application piles.
