Stability analysis of a tunnel using LIDAR data and the keyblock method
Abstract We describe a stability study for a tunnel excavated in a fractured rock mass. The proposed methodology uses automatic and semi-automatic algorithms to extract joint sets from a LIDAR point cloud. Using that information and considering a model of ubiquitous joints, pyramidal and non-pyramidal unstable blocks were identified using the keyblock method. The algorithms used for the stability analysis were implemented in BLOFOR software, which represented the possible location of the blocks in the tunnel in three dimensions and provided information on tunnel stability, including a safety factor for each block.
