Abstract

In this research, upward seepage flow tests and analysis have been performed for the model ground with or without a sigle pile, in order to investigate the effects of gravel piles on the stability of surface soil against so-called secondary liquefaction. The results calculated by analytical procedure are in good agreement with the experimental results for every case tested in this research. Finally, authors estimated the effects of gravel piles against secondary liquefaction by calculating bearing capacity of the improved ground considering excess pore pressure in the ground.
