The document summarizes a presentation on the conceptual design of the Chenab Bridge in India. The bridge will be the longest railway arch bridge in the world, crossing the Chenab River between Bakkal and Kauri in Jammu and Kashmir. It will carry two railway tracks on a steel girder deck designed to withstand winds up to 100 km/h for at least 120 years. The bridge's design and construction methods had to overcome challenges from the mountainous terrain and lack of local infrastructure.
Chenab Bridge
- 1. Presentation on Conceptual Design of Chenab Bridge Nilesh Bhosale M.Tech. Transportation Engg.
- 2. Content Basic information of bridge The bridge site Description of bridge Design of bridge Construction method Conclusion
- 3. Basic information of bridge The Client KONKAN RAILWAY CORPORATION LTD, India Location Crosses Chenab river between Bakkal and Kauri,in Reasi district of Jammu and Kashmir The contractor Afcons Infrastructure Ltd, Mumbai, India The Official Project Name Design & Construction of Special Bridges across the River Chenab at km 50/800 on the Katra-Laole section of the Udhampur-Srinagar-Baramulla Rail Link Project
- 4. Bridge Site Site is located in mountainous region of Jammu Kashmir
- 5. All the traffic in the region is running through narrow road network, which is crowded and dangerous. The bridge is a part of the new railway connection.
- 7. Deck will carry two railway tracks Superstructure is a steel girder
- 8. Design of Bride The design speed of the railway was set to be 100 km/h and the design life had to be 120 years. Fatigue assessment shall be done as per BS: 5400 Part –10. Wind loads is derived using physical topographic models of the site and tests in a wind tunnel laboratory. The superstructure is a plate girder with a closed deck, where rails are connected. The closed deck keeps the rainwater out and provides mostly dry environment below the deck.
- 12. Construction method Insufficient infrastructure. Workshop, Paint shop and Electricity generation. Cable crane (Capacity 40 tonnes) Steel decks Derrick crane (Capacity 100 tonnes) Erection of arch segments
- 15. Typical arch erection by derrick crane.
- 16. Erection of last span and key segment by cable crane.
- 18. Conclusion The design of the main arch requires consideration of a number of additional parameters, such as fatigue , stability, composite action, etc. The Chenab Bridge will be the biggest / the longest-span / the highest railway arch bridge ever built in the world. Its design offered great challenges to the design team.
