Experiment E7/0,3 – Time Behaviour of Active Pressure of Non-Cohesive Sand after Wall Translative Motion

摘要

A new experiment denominated as E7/0,3 with active pressure of non-cohesive quartz sand on a rigid moved wall was performed at the Institute of Theoretical and Applied Mechanics in the last year. The wall was translative moved towards active direction (out of the mass) at a position of supposed acting of active pressure value, then the wall motion was stopped and time pressure stability was monitored. After more than three months the wall was moved at the last position of 100 mm from original position before the experiment. The experiment ran four and a half months. The paper will present the first results of monitored active pressures of sensors during a consolidative phase after active wall movement of 1.357 mm. The experiment was repeated to prove the results (Experiment E8/0,3).
