Changes in pore water pressure of compacted soil from a viewpoint of the behavior of entrapped air
Transactions of The Japanese Society of Irrigation, Drainage and Reclamation Engineering
Cohesive red soil of high water content was compacted in a mold and change in pore water pressure was observed. The pore water pressure at the bottom of the specimen was at first very high just after compaction and then it decreased very rapidly. The pressure continued to decrease and finally approached a negative constant value. Several experiments were conducted to investigate the reason for such a phenomenon. Increase in bulk volume of specimen and height of soil skeleton were observed afterdoi:10.11408/jsidre1965.2004.303 fatcat:imtooc65gjhwngywtl5c3lzmgm
