Study Index Properties of Soil from Geotechnical Test in their Relation to Landslide

Abstract

There are many methods in assessing landslide, one of them is examine the properties of soil. In this research measured several test on soil sample i.e. unit weight, Moisture content, Hydrometer test. The unit weight test yields a value ? is 13.63kN/m3, water content value is 4.51%. Furthermore, the sieve analysis test and hydrometer analysis were carried out to determine the type of soil in the study area, namely little sandy silt. The combination of a steep slope with the type of material that makes up the slope makes the slope prone to landslides. Creep often occur in the slope, which are caused by vibrations from vehicles at the foot of the slope. This condition will make the slope even more unstable because the geometry of the slope will become steeper.
