2. INTRODUCTION
 The kishanganga hydroelectric plant is an $864 million
Rs. 5783.17 crore dam which is a part of a run-off-the-
river hydroelectric scheme that is designed to divert
water from the kishanganga river to a power plant in the
Jhelum river basin.
 It will have an installed capacity of 330 MW
 Construction began in 2007 and was expected to be
completed in 2016
 Construction on the dam was temporarily halted in 2011
by the Hague’s permanent court of Arbitration due to
Pakistan's protest of its effect on the flow of the
kishanganga River (called Neelum river in Pakistan)

3. PROJECT LOCATION
 It is located 5km north of Bandipora 90 km from
Srinagar .
 The water is diverted from kishanganga river
located in Gurez valley nearly 90 km from
Bandipora towards the power house located in
Bandipora through the 24 km tunnel

5. DESIGN
 The project includes a 37m (121 ft) tall concrete-
face rockfill dam which will divert the portion of
the kishanganga river south through 24 km
tunnel.
 The tunnel is received by a surge chamber
before sending water to underground power
house which contains 3×110 MW pelton turbine
generators.
 After the power plant, water is discharged
through a tail race channel into Wular lake
 The drop in elevation from the dam to the power
station will afford a hydraulic head of 697 m
(2287 ft).

6. HEAD RACE TUNNEL
 The head race tunnel (HRT) is 23 km long of which
14.6 km is done with tunnel Boring machine (TBM)
rest of which it is done with blasting

7. EQUIPMENTS USED FOR TUNNELING
 14.6 KM of the tunnel excavation was done with
the Tunnel boring machine (TBM)
 And rest of the excavation was done using tunnel
drilling jumbo machine by drilling and blasting
method

17. ROOF STEEL TRUSS
 Trusses are triangular frame works in which the
members are subjected to essentially axial forces due to
externally applied load.
 The location of the building is in hilly areas of j&k
therefore steel trusses are usually preferred due to high
snow load.

18. LOADS ACTING ON ROOF TRUSSES
 The roof trusses in buildings are subjected to the
following loads
 Dead load: self weight of truss including the purlins
,GI sheets (roof cover),bolts .
 Live load: the live load on the roof truss consists of
the gravational load due to erection and servicing as
well as dust load etc. and the intensity Is taken as per
IS:875-1987(Reaffirmed 1992).
 Wind load: wind load on the roof trusses, unless the
roof slope is too high, would be usually uplift force
perpendicular to the roof truss due to suction effect of
the wind blowing over the roof. Hence wind load on
the roof truss usually acts opposite to the gravity
load.

19.  Earthquake load :the loads are calculated as per
IS:1893-1985
 Snow load:
