ABSTRACT:

Landslide is a natural disaster that occurs when rock, earth, or debris flows to downward slope due to gravity after being detached from slope underneath. It is essential to know the geotechnical properties to analyse the causes of landslide. For the present study geotechnical investigation has been carried out on the slopes of Lonavala and Tamini Hill, Maharashtra . Results obtain from laboratory test and field investigation revealed that the underlying causes of the landslide could be (a) the geological formation of those hills (b) permeability through the different layers of soil (c) shear strength of the soil (d) cutting of hills slope for reconstruction and widening of the road. Landslide triggered due to heavy precipitation during the monsoon season. In north eastern area of India is mainly hilly that’s why recent development is going on here. Due to this reasons road construction is going on here. As the whole range is composed of siltstone and mudstone mainly loosely deposited soil they are cutting the hills vertically which unstable the slope. After the thorough investigation we have seen that mainly shallow landslide happen on those two hills.
