Abstract
Adverse tunnelling conditions may arise when active landslide processes are encountered at or near the excavation site. Such slope hazards act to increase the complexity of the geotechnical conditions, induce tunnel instabilities, cause costly delays, interference with construction logistics and shorten the life span of the final structure. Consideration must also be given to auxiliary structures, for example the influence of slope hazards on access roads, secondary adits and shafts. In this paper, a case study from India is presented to demonstrate some of the difficulties arising from tunnelling within an active landslide region.
