Abstract

According to the large quantity of in situ measured data,the characteristics and variation laws of displacement and load of bolts in the surrounding rock are studied,and the factors which influence the displacement of surrounding rock and the load along bolts are analyzed as well.
- underground cavities,
- displacement of surrounding rock,
- load along bolt
