Slope movements are dynamic phenomenon which are complex in time and space. Slope failure generally occur in hilly regions like Himalayas. It is dangerous because of the sudden movement of the slope-forming material called as landslide. The advancement in defining the characteristics of complex rock slope failure using numerical techniques have proved to be important tool for understanding the processes involved and the associated calamaties. The present study mainly deals with the Static dynamic analysis of Mansa Devi hill landslide, Haridwar, Uttarakhand, India. The area experiences local as well as regional slides every year. The digital elevation model is made and Laboratory experiments were conducted to determine the various mechanical property of rock mass. The geotechnical parameters have been used as input for the numerical simulation of slope using FLAC3D. For dynamic analysis a sinusoidal wave of frequency 2 Hz and acceleration of amplitude 0.02 applied to model and observation was taken at 5, 10 and 15 second. The displacement along all the three direction and stresses along critical xx and zz direction have been calculated. Finally factor of safety of study area is calculated. The study indicates that slope at the higher height along the slope is unstable and it is stable at the lower height. The effects of instability have been thoroughly considered. |
