Reliability analysis of block fall in unsupported hard rock tunnels
Abstract: Underground structures such as tunnels require control and maintenance in order to ensure the appropriate use. A methodology for assessing the risk of block fall in unsupported tunnels was proposed using the reliability analysis, First Order Second Moment (FOSM), with the Unwedge software. This paper deals with a particular tunnel of the rail Vitoria-Minas Vale Company, Espirito Santo State,...
