Rocscience

Phase² is widely used for the analysis and design of underground tunnels. Applications include tunneling in hard rock, weak rock, jointed rock and soft ground. Multi-stage analysis and advanced support design tools simplify the design of tunnel lining systems.

Unwedge is used to determine the stability of rock wedges formed by the intersection of structural discontinuities with underground tunnels, excavations and caverns. Factor of safety is calculated and support requirements can be determined.

RocData is a versatile toolkit for the analysis of rock or soil strength data. Failure envelopes can be generated for a variety of strength criteria including Hoek-Brown and Mohr-Coulomb. Results can be used as input for other programs such as Phase².

Dips is a stereonet program for the analysis and presentation of structural data. Joint sets can be determined for tunnels in jointed rock. Kinematic analysis of wedge stability can be examined or results can be used as input for Unwedge.
