The slide has occurred due to the slope disturbance that leads to the infiltration of water along the weak planes along with intersection of joint forming wedges towards the road side are the causative factor for failure.

1.Deep hillside lined ditches on toe of slope may be constructed and maintain regularly so that water does not flow on the road bench. 2. Reducing the general slope angle by slope dressing at the crown portion of the slide may be considered.
Extensive slope cut and the prolonged percolation of water along the weak planes resulted the planar failure of rock, .
