Evaluation of Long-term Behaviors of Abutment and Transition Zone with Cement-treated Gravels during Construction
2018
Korean Society of Hazard Mitigation
Preserved Fulltext
This study measured the horizontal earth pressure on the boundary between an abutment and transition zone with cement-treated gravels over 16 months during the construction of the Osong test line. The internal friction angles were back-calculated from the measured horizontal earth pressure based on the Rankine active earth pressure theory. They were in the range 38°-58° with an average of 46°. This value is 11° higher than the internal friction angle usually used for the design of an abutment.
