[III-273] Estimation of creep parameters by deformation measurement of borehole diameter
Keywords:creep, borehole, in-situ experiment
We developed the displacement meter to measure the diameter of the borehole in order to evaluate the creep parameters of the rock mass. And measured the borehole diameter at three tunnel sites. Creep diformation was observed at each tunnel sites. By FEM, fitting analysis was performed on the time history of displacement measured. As a result, it turned out that there was a high possibility of setting creep parameters from the result of the displacement meter.
