Geologically, the affected site is comprised of highly weathered and friable sandstone overlain by insitu soil cover.  Extensive slope excavation beyond the critical angle and toe removal of natural slope having weak slope forming material played a major

A large number of minor cut slope failures were observed along this section. Proper mitigation should be taken up to curb untoward incidences.

1. Moderation of slope gradient may be considered.
2. Construction of hillside lined draiNGe.
3. Dressing of slope and removal of depleted mass from the affected slope.

Destabilization caused due to ill modification of slope face and toe removal for road construction, unfavorable lithology and weak slope forming material, reduction in shear strength of slope material due to oversaturation are the main geoscientific caus
