| Abstract: | Rock anchors are the cornerstones of modern geotechnical engineering. Adequate dimensioning will both reduce cost and improve safety. We here present microseismic monitoring results of rock anchor uplift tests at full scale. The uplift tests were monitored with a network of surface geophones, amongst other sensor systems. These geophones recorded the failure of the rock mass during uplift. Our results show that this approach gives valuable insight into the fracture evolution in time and space. A main fracture cone develops at a 23 ∘ angle, and a secondary fracture cone at a 35 ∘ . Highlights: Three uplift tests of rock anchors at full-scale were monitored by geophones to track and characterise the failure of the rock mass. Microseismic events were detected and located, and the development of microseimicity was compared with the anchor load and vertical displacement. The rock mass is fractured in a conic shape around the anchor. [ABSTRACT FROM AUTHOR] |
