Stability of Underground excavations

The ultimate bearing capacity of the primary support is considered in analogy with the treatment of reinforced concrete. A computer programme has been developed for this purpose. The programme facilitates computation to the influence of primary support on the stress and strain condition. The computation of stress and strain conditions for underground room profile excavation is performed by the Boundary Element Method. The method is a timesaving procedure for used to define the problem in design process, it offers flexibility in assumptions on input parameters characterising the massif, and in observing the influence of changes on the stress and strain conditions
