Abstract
This research introduces a laboratory creep test for measuring displacements under constant load for long periods of time in anchors embedded in soft rocks. The preliminary theoretical and experimental ideas that have served for the design of the equipment are detailed, as well as its mechanical and geometrical characteristics, defining the test procedure. A rocklike material composed of bentonite, cement and water has been tested, which has been geotechnically characterized by identification, strength and deformability tests. The specific manufacturing process of the test samples is also defined. Three creep tests are carried out with durations between 46 and 75 days each, observing their reproducibility. An adequate contrast results between the instantaneous displacement obtained with the test and the obtained with the analytical solution under the same boundary conditions.
