A METHOD TO CALCULATE EXCESS PORE PRESSURES AND SURFACE SETTLEMENTS OF THE GROUND IMPROVED BY GRAVEL PILES

Abstract

In this research, a new designing method of gravel pile systems against liquefaction of level ground during earthquakes is proposed. The proposed method has some advantages over the existing methods. Small scale vibration tests were performed in order to verify the applicability of the proposed method. As for the behavior of excess pore pressures in the improved ground and surface settlements of the improved ground, experimental results indicated satisfactory coincidence with calculated results.
