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 Atharamura and Baramura Hill, Tripura. Results obtained 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.
