However unlike the mechanical anchor the bonded anchor must also include a bond length in the embedment depth The bond length allows the applied tensile load to be transferred to the surrounding rock Therefore the embedment depth of a prestressed bonded rock anchor is made up of the free stress length and the bond length When using the rock cone method a
