A fracture propagation code and its applications to nuclear waste disposal
2004 (English)In: International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, ISSN 0148-9062, Vol. 41, no 3, 448-449 p.Article in journal (Refereed) Published
A two-dimensional fracture propagation code, FRACOD, has been developed. It is based on the original work by Shen and Stephansson (1994) and FRACOM Ltd. (2002) and predict the explicit fracturing process such as fracture initiation and fracture propagation in rock masses. This paper describes the theoretical formulations and the recent developments of FRACOD. The code has been recently used to study rock mass stability for nuclear waste disposal problems. Two case studies are presented in this paper. The first case study is to predict the pillar stability for the Äspö Pillar Stability Experiment (APSE, Sweden) which is designed to test the spalling behaviour of a pillar between two deposition holes under excavation and high thermal stresses. The second case study is to analyse the stability and the extents of Excavation Disturbed Zone (EDZ) of a vertical shaft and horizontal gallery at MIU site in Japan. The results of the two case studies are presented and discussed.
