Abstract:The hollow grouted bolt can improve grouting pressure by hollow bolt bar. Contrast has been done between hollow grouted bolt and full-length bonded one in reinforcing high slope of K60+535–K60+585 of road S246 in Xin¢an county,Luoyang City,Henan Province. There is limestone in this area,and joint develops strongly. There are two kinds of bolt in reinforcing the slope. Analysis has been done according to grouting pressure,grouting volume,the maximum tension force and the displacement. The maximum value is 181 kN for the hollow grouted bolt,and the full-length bonded one is 183 kN in the common fractured areas,but in the strongly fracture areas the maximum values is 179 and 153 kN,respectively. And the distributions of axial and shear force in the bolt are analyzed by the UDEC software.
