- Abstract
Anchorage system can transfer or enhance intensity and steady ability of the geotechnical project. Based on the simplification of a project, the process of anchorage and failure of bolt is simulated in laboratory. The analytical expressions of stressed bolt in elastic rock under axial symmetry condition are deduced. The pilot study of the relativity of anchorage stress and acoustic parameter is discussed by ultrasonic transmission way in this paper.
