Identification of Landslides Zone by Spatial Based Mapping and Plaxis Modeling

Abstract

Landslides are the natural disaster where a mass of soil/rock slides down from the higher to the lower place under the influence of gravity and water. This accident has caused a lot of victims. Therefore, an earlier estimation is needed in order to identify which spots/locations are vulnerable to this disaster. One of the ways to identify those spots i.e. by mapping. In this research, the mapping was done by utilizing the spatial-based technology i.e. the Drone technology to record the location's image which vulnerable to be devastated by this disaster. From the mapping results, an image of the slope will be obtained. This image is next to be plotted and modeled manually by using Plaxis Software. Then, the modeling results will be analyzed especially when the slope was having some failures. Aside from analyzing with Plaxis, the slope failures are also influenced by the mechanical and physical properties of soil. Therefore, laboratory tests were necessary. Laboratory tests were purposed to obtain the physical and mechanical properties of soil. The final analysis result by using Plaxis was the safety factor from those chosen spots.
