“…One of the natural factors is climate, which causes the slope shear strength to decrease to a critical limit, causing landslides. Climate and weather factors have an important impact on the process of landslides because they can change slope stability conditions through increasing pore water pressure and the degree of saturation of the slope materials (Juliantina et al, 2018). This increase in pore water pressure is also often caused by intense rainwater on slopes so that slopes with high Abstract Slope stability analysis is particularly important for natural slopes that are relatively undesigned to be technically safe.…”

Slope stability analysis is particularly important for natural slopes that are relatively undesigned to be technically safe. Natural slopes are prone to collapse depending on the condition of the slope material and rainfall. A comprehensive stability analysis using numerical methods to calculate the factor of safety and probability of collapse can be used as a reference to assess the safety of a slope. This study discusses boundary equilibrium and finite element in the analysis of slope safety factor and landslide probability by reconstructing the slope with landslide history. The reconstruction of the slope is based on the actual slope condition with saturated material due to rain that has a safety factor of 0.5 using mathematical methods which are then analyzed numerically in this study. The results of the factor of safety on the saturated condition slope have a value that is not much different from the actual condition with a 100% probability of landslide. The results of low shear strength values in each slice of the limit equilibrium analysis for saturated conditions also indicate that the slope is in an unsafe condition which is supported by the development of shear and tensile strains in the finite element method analysis in the slope slide plane area which causes the stress distribution in the actual landslide area to be unstable.

Excavation work is a type of work that is commonly found in many construction projects. In carrying out excavation work, it is necessary to consider stable slope conditions so that landslides do not occur during work. Common ground excavation work found on Bangka Island, especially in the city of Pangkalpinang, is kulong excavation, or sea excavation, as an effort to increase depth elevation. This study aims to determine changes in soil slope stability due to excavation work at a certain depth and slope. The study used field observation data in the form of CPT (Cone Penetration Test), hand drill, and data from laboratory analysis. Data analysis was then carried out using the Slope/W software, which is part of Geostudio 2018, to determine the safety factor for soil slopes using the Bishop and Fellenius method. The value of the safety factor produced by Slope/W determines the level of stability of the soil slope. The slope of the soil varied 15⁰, 30⁰, and 45⁰ and the excavation depth was determined to be 4 m and 8 m. The results showed that the safety factor of the 4 m and 8 m excavation depth in the same slope angle was decreasing about 23.18 % while the safety factor of the 15⁰ and 30⁰ excavation slope in the same depth was decreasing about 31.81%

Landslides are the downward movement of materials under the influence of gravity when shear stress exceeds the shear strength of the material. It includes various movements resulting in complex type of slope failures which commonly occurred on cut slopes of Ghat roads in mountaneous region. The study area chosen for the geotechnical investigation is Kolli hills situated in the tail end of the Eastern Ghats in Namakkal district of Tamil Nadu, India. The ghat road section of 20 km stretch along with 70 hairpin bends, connects the foothills at Karavallikkombai to Sholaikkadu at the top is selected for the present study. The hill is situated at a fault zone which is extended from Mettur dam, Salem district, Tamil Nadu. In this study, undisturbed soil samples were collected from 10 landslide locations and tested for its index and engineering properties. Based on the test results, static slope stability analysis using Modified Bishop method and dynamic slope stability analysis using Simplified Newmark method were carried out to find out factor of safety of the slopes which is used to derive the slope stability assessment of the study area. The landslide hazard zone assessment was carried out to identify the landslide prone areas.
