    INTRODUCTION TO EARTHQUAKE ENGINEERING Earthquake engineering is the science of the performance of buildings and struc- tures when subjected to seismic loading. It also assists analyzing the interaction be- tween civil infrastructure and the ground. One of the most important aims of earth- quake engineering is the proper design and construction of buildings in accordance with building codes, so as to minimize dam- age due to earthquakes. It is the earthquake resonant wave frequencies of seismic engineer who ensures proper design of waves, thus reducing the damaging effects. buildings, so they will resist damage due to Thus, the structure is protected from the earthquakes, but at the same time not be damaging consequences of an earthquake unnecessarily expensive. by decoupling the structure from the shak- ing ground.

    000_COVERS.qxd 2/13/1950 7:25 PM Page 3 000_COVERS.qxd 2/13/1950 7:25 PM Page 4 I take this opportunity to congratulate the USBRL team for appreciable work done on the project in the last one year and for bringing out the publication of the 12th issue of this Technical Magazine Himprabhat. The Udhampur-Srinagar-Baramulla Rail Link (USBRL) is a treasure trove of knowledge, new techniques, state-of-the-art technology and varied experience for engineers and is, thus, a unique project in the annals of Indian Railway. The magazine not only provides the details of experience gained during the course of implementation of the project but also provides a platform for the project team to share their views. This is a very commendable effort for documenting the important facets of challenges in the Himalayas for contemporary professionals as well as for posterity. I hope that USBRL maintains the momentum and spirit and continues to move forward in realisation of dreams of connecting Kashmir valley to the Indian Railway network as well as to take forward this fascinating journey of publication of a magazine to enrich all experienced and young engineers alike. I am glad to see the 12th issue of Himprabhat Technical News Magazine giving an account of the achievement of technical marvels and the challenges faced by the USBRL Organisation of Northern Railway. The USBRL team has had a breakthrough in tunneling efforts, excavating 26.34 km in 2018-19 against last year’s progress of 17.05 km, which is 54.5% more compared to last year.

  • Srinagar – Baramulla – Rail Link Project in Union Territory of Jammu & Kashmir
    KATRA- DHARAM SECTION OF UDHAMPUR – SRINAGAR – BARAMULLA – RAIL LINK PROJECT IN UNION TERRITORY OF JAMMU & KASHMIR 1. Overview: Udhampur - Srinagar - Baramulla Rail Link (USBRL) Project is a National Project to provide rail connectivity from rest of the country to the beautiful valley of Kashmir. A part of this project from Katra - Dharam km 30.00 to km 72.935 & km 91 to km 100.868 has been assigned to Konkan Railway Corporation Ltd. for execution. It comprises of 45.24km (86%) of route in tunnels, 4.6 km (9%) of route on bridges and balance 5% of route in cuttings and embankments. Konkan Railway had made 164km of roads including road tunnels and many temporary Bailey bridges. To expeditiously execute the project Konkan Railway has set up Project Head Office at Jammu. Its project camps are located at Reasi, Kauri and Sangaldhan. KRCL has mobilized a team of about 290 staff and Engineers for taking this project ahead. The construction machinery, plant, equipments, materials, technicians, skilled and un-skilled manpower is arranged by KRCL’s construction Contractors. For design support, various National and International agencies have been engaged. 2. Difficult Geology: The alignment is passing through three major geological thrust zones namely Reasi, Muree and Panjal thrust. The geological strata varies from loose conglomerate, clay, silt stones, crushed and faulted and stones and dolomites. Geology changes very frequently along the alignment and it is very difficult to access the complete geology in advance. Hence, as the work progresses adjustments in design have to be made. 3. Special Bridge -Chenab Special bridge across the river Chenab (under construction) is being built at height of 359m, from the bed level.
