Q-System (tunnelling) MOD APK v3.0 (Pro Unlocked)

Q-system is a tunnelling method used to construct underground tunnels. It was developed in Japan in the 1970s.

The Q-system is a shield tunneling method. A shield machine is used to excavate a tunnel and the surrounding soil is supported by an array of pipes, called a “jacking frame”. The jacking frame is connected to the shield machine and pushes it forward as it excavates the tunnel.

The Q-system is used to construct both road and railway tunnels. It has been used to construct some of the world’s longest tunnels, including the Gotthard Base Tunnel in Switzerland and the Seikan Tunnel in Japan.

Q-System (tunnelling) App Overview and Details

Gecko Geotechnics has developed a mobile phone application for empirically design ground support for tunnels and underground excavations using the Q-system. This application provides interactive input menus, background reading, and graphical outputs (Q-support chart & Modulus and Support Pressure chart). It also allows for emailing of automatically generated reports.

The Q-system (Barton et. al. 1974) was developed 40 years ago for describing rock mass quality in a quantitative way, using six important parameters and ratings of quality. These were first related to structural geology, in particular the number of joint sets, their roughness, whether there was clay-filling, followed by the effects of water and the stress/strength ratio. A logarithmic-like scale from about 0.001 to 1000 was the result. All the ratings of the key parameters are given in this guide, and include footnotes and a field-logging sheet and examples of its use. Linked to the Q-value and the span or height of the excavation in rock, and also reflecting the final purpose of the excavation, is an updated chart of recommended support and reinforcement for the arch and walls of underground excavations. Both tunnels and caverns are catered for, from roughly 3m to 60m span. Some 20 years ago the S(mr) support was updated by the same authors, replacing mesh reinforced shotcrete with fiber reinforced sprayed concrete or S(fr). The recommended PVC-sleeved (CT) bolts were more resistant to corrosion. The Q-system has always reflected single-shell B+S(fr) concepts of permanent support, as encompassed in the Norwegian Method of Tunnelling (NMT). During the 40 years of its use the Q-value has been shown to have empirical relationships to seismic velocity, deformation modulus, and tunnel or cavern deformation.
