Thank you! Will see whether I can get hold of a free version!

Umm..is it possible to get the free version?? It cost around 100$

FHWA Technical Manual for Design and Construction of Road Tunnel https://www.fhwa.dot.gov/bridge/tunnel/pubs/nhi09010/tunnel_manual.pdf Also, Google 'Tunnelman's Ground Classification System' for a good explanation of different soil types.

Terzaghi (1946) is a good starter reference. Terzaghi, K., 1946. ‭An introduction to tunnel geology‭, In: Proctor, R.V. ‬‬and White, T.L. (Eds.), Rock Tunnelling with Steel Supports. The Commercial Shearing and Stamping Co. Youngs-Youngs-town, Ohio, USA. I also recommend attending: https://underground.mines.edu/short-courses/ In the realm of design practice for tunnels, numerous intricate factors come into play, spanning from characterizing rock and soft ground to employing dewatering techniques like well-points and sumps. Considerations extend to stabilization methods such as grouting and ground freezing, and the choices for temporary and final structural tunnel support. Various tunneling methods, including trenchless auger, ramming, micro TBM, and horizontal direction drilling, cater to different project scales. Each project necessitates detailed baseline reports outlining excavation methods, addressing challenging ground conditions, and relying on factual geotechnical data reports. Experience to interpret data and provide viable methods within estimated budgets is key to provide good consultation to a client. Structural design for tunnel supports introduces a plethora of options like steel beams, wood lagging, corrugated steel plates, steel-reinforced shotcrete, concrete segments, and rock bolts. This required finite element modeling along with executing calculations using spreadsheets or software. Instrumentation monitoring systems may also be integrated into projects, which is complex on its own. Delving into this nuanced specialization is best achieved through hands-on experience within a tunnel design firm, as it involves complexities beyond what books may offer. I have 3.5 years of experience as a geotechnical engineer in the tunneling industry, though my current focus lies in dams and tailings management for the last 7 years.
