The various factors and how they influence the loading and deformation of supports needed in deep tunnels in weak rocks are presented. Broadly, these are the rock and water conditions and their response to excavation, the excavation and support timings and procedures, and the support details and their workmanship. Particular attention is drawn to the need to consider the truly three-dimensional influence of rock discontinuities on excavation collapse mechanisms with the aid of models and field… Expand
