| Research Abstract |
Ultra-high resolution fiber-optic strain sensor was developed, and we demonstrated the static-strain resolution of the developed sensor to be 2. 6×10^<-9>. The sensor was applied to the actual rock mass environment at Aburatsubo, Japan, and we successfully measured the strain on the order of ten nano-strain, of which baseline length was 1 m. We also derived thermodynamically consistent constitutive equations for the coupled two-phase flow and deformation processes of porous media, and developed a numerical simulator based on the derived constitutive equations.
