Design of a railway tunnel parallel to an existing tunnel

摘要

Mumbai Rail Vikas Corporation Limited has planned to construct 5th and 6th railway lines from Thane to Diva. On the route, the rail line passes through various geological features like creeks, lineament, hills and flood creek plains. Because of the varied topography, various structures like bridges, foot over bridges and runnels are to be constructed. As per the Geotechnical investigation report, two tunnels are planned on the route.
