| Abstract: | This paper examines a typical gneiss forming the foundation Xiaowan Hydropower Station.Grinding test is ued to analyze the formation environment and mineral composition of the biotite granite gneiss.The results confirm the relationship of the rock strength with its mineral content and mineral strength.Furthermore,acoustic emission is carried out during the uniaxial compression tests of the biotite granite gneiss samples.The acoustic emission process is examined during the biotite granite gneiss instability ... |
