英文摘要 | The finite element simulation of sub-crack development around a fracture cemented with grout in Fangshan marble plate specimen under uniaxial compression is carried out. The initiation, coalescence and recovery of sub-crack around as well as inside the cemented fracture are photographed and analyzed under real-time scanning electron microscope observation. Finite element computation of the crack process using NOLM program with a strain-softening constitutive model of low tensile strength is performed. The computation result represents the experimental observation fairly well. The real fracture or fault system in earth, no matter in small or large scale, has filling materials such as fault gouge or fault clay which has lower strength. Compared with the field observation, the cemented one should be a better simulation of the actual geological situation. Therefore the results give a more comprehensive understanding and simulating of fracturing process in geologic structure.; EI; 0; 13; 2350-2356; 24 |
