项目名称: Experimentell och teoretisk studie av skaleeffekten p� bergmekaniska parametrar f�r bergsprickor
摘要: Mechanical parameters for rock fractures are crucial in rock mechanic dimensioning. Under certain circumstances, these parameters may vary by scale. The understanding of this scale effect is inadequate and the project aims at reducing ambiguity by performing large-scale shear attempts in laboratory environments. An important part of the work is also to develop and test self-made specimens (replica) with mimetic properties. The replica gives the opportunity to repeat experiments, which gives the opportunity to better understand how and why the rock mechanical properties are affected. The trials will be carried out in a completely new large-scale shear box. In parallel with the experiments, theoretical development of existing and new theories as well as numerical modeling will be carried out with the aim of obtaining theories that can describe how rock mechanical parameters vary with the scale. The project concerns funding up to a licentiate degree for an Industrial PhD student at SP.
