Swellex Rock Bolts: Support Efficiency by carlosfilipegomes3994 is a document available to read on EtoBox.
Swellex rockbolts provide much greater support than grouted rockbolts right after installation, helping stabilize the rock mass near the tunnel face. Swellex controls deformation and plasticity better in continuous rock. In heavily jointed rock, Swellex improves stress continuity and the formation of the natural rock arch around the tunnel. Numerical modeling confirmed Swellex generates more support with a shorter plastic region compared to grouted bolts. For the Tomei tunnel project, Swellex rockbolts were
