This paper presents Safety Analysis of Rupsiabagar Khasiyabara dam situated in Pithoragarh district of Uttarakhand in India, using CADAM. The purpose of this work is to see the impact of earthquakes on dam structure & if require modify it by seismic retrofitting to improve the resistance of dam to earthquake. The safety Analysis of concrete gravity dam owes continuous concern to dynamic seismic activities due to earthquake. These Earthquake results in change in seismic parameters due to tectonic movements. CADAM software has been primarily designed for structural stability evaluation of concrete gravity dam using pseudo static method & pseudo dynamic method.
Rupsiabagar-Khasiabara dam is located on river Goriganga, which is originates from the Milam glacial regions of Himalayas and has tremendous scope for development of hydro-power, which needs to be harnessed to meet the ever-growing demand for power.
With reference to the present value of Peak Ground Acceleration, seismic hazard analysis for Rupsiabagar-Khasiabara dam has been performed .The section of dam is checked for present value of Peak Ground Acceleration for stability for various loading conditions and was found safe with the present study.
