Cover Picture:

Lining stress controllers (LSC) have been developed as special supporting measure for tunnelling in zones with stress-induced failure involving large ground volumes and large deformations. The shotcrete lining is divided into several segments by longitudinal construction joints. The purpose of this segmentation is to absorb large deformations occurring during tunnel driving in weak ground. LSC elements are installed into these deformation joints. These elements have a defined workload during compression so the primary lining is not damaged (Source: DSI Underground).
