  • Rock Bolt - an overview | ScienceDirect Topics

    Rock bolts are a type of drilled soil nail or anchor used when the ground to be stabilized consists mostly of rock materials. These types of inclusions are typically grouted in place and posttensioned, similar to soil anchors (Figure 15.8).The bolts hold potentially unstable jointed or fractured rock masses together in compression with bearing faceplates providing passive resistance, forming a ...

    Rock bolts have been used during underground excavation in the mining and tunneling industry for well over 100 years. They provide temporary roof support and also keep walls secure. Today, rock bolts are used in many other applications. These include reinforcing concrete dams, bridge abutments, rock cliffs, steep slopes, and stabilizing road cuts.

In a dilating rock mass the maximum bolt load usually occurs at a distance of about 0.5 m from the face plate. Rock bolts are subject to both pull and shear loads in situ. The shear strength of a rock bolt is equally important as its tensile strength.

Once drilling is done and this steel bolt is inserted, cement grout or resin grout can be used as the grouting agent. For reinforcement, a cable bolt made of steel wires intertwined as a steel rope is placed with the grout in the borehole.
