Stresses, Deformations and Progressive Failure of Non-Homogeneous Fissured Rock
The objective of the research program is to develop computer programs, using the finite element method, to predict stresses and deformations in the vicinity of underground excavations. The computer programs should allow for arbitrary initial stresses in rock, arbitrary shape and size of the opening, any given sequence of construction, non-homogeneous material properties, interaction of rock with supporting structures, progressive damage and time dependent deformation and load development on supporting structure. Limited experimental work to verify key points in the theory is planned. Research during the first year is directed towards literature survey, selection of mathematical models for behavior of rock and development of computer programs for elastic-plastic, elastic-brittle rock and for progressive failure of rock around underground openings. At this reporting, selection of mathematical models has been completed. (Author)
