The moderately weathered and jointed rock mass exposed on cut slope is predominantly composed of muscovite schist. The two sets of joints on the slope are persistent; where  J1 is valley dipping and J2 is dipping inside the hill. J1 is chiefly responsibl

1. Removal of loose blocks of rock from the affected slope. 2. RCC retaining wall for toe support with sufficient weep holes.
1. Adverse condition of rock mass: toe of the cut slope exposes two prominent sets of joint. 2. Seepage of water along weak planes during rainfall events. 3. Rock slide along the valley/ road dipping joint plane. 4. Ill-planned modification of slope for
