On July 15, 2020, a portion of approach to Sattarghat Bridge (Ram Janaki Pul) in Bihar, India on Gandak River that was inaugurated a month ago collapsed after water flow increased in the river due to heavy rainfall. The main bridge of the Sattarghat Bridge plan is intact but a culvert (an 18 m long minor bridge) connecting the approach road to the bridge was unable to withstand the pressure caused by the rising levels of the river and was washed away.

#Lining Design Consideration Alignment Tunnel Supports Material durability structural loads Ground Reaction Curve Support Characteristic Curves Structure Type_Tunnel Field_Bridge Category_Knowledge
Hey readers… we always come across some or the other type of tunnel, be it city metro lines, railway or roadways tunnels, but what keeps the tunnel standing intact during its operational life is its support system. Tunnel linings, temporary, primary or permanent, constitute the support system of the tunnel or shaft. In my previous article ‘Guidelines for Tunnel Design’, I had presented some basic design considerations and highlighted Research Design and Standards Organisation (RDSO) specifications for tunnel design. Now in this article, we would proceed further towards understanding tunnel support system and what could be the essential considerations for the design of tunnel linings.
