Abstract

Slope is (part of) the side of a hill or mountain. Slope stability became the main concern while working on a construction project, especially on road/highway project. Slope stability determined by soil parameters which include: physical & mechanical behavior of the soil, ground water level, rock mass structure, etc. Because there is an uncertainty on parameters value in the slope design, causing the slope vulnerable, it needs a concept such as probability analysis to find the stability of the slope. Probability analysis using Monte Carlo method involved a few parameters such as unit weight, cohesion and friction angle. Soil and Slope Geometry data were obtain from prior research. In this analysis there are three trials conducted with various slope angle along with similar material. The result will show a safety factor and failure probability percentage. From this analysis, it can be concluded that the steeper the slope, the lower safety factor number will be shown. The contrary result applied on probability of failure, the steeper the slope, the bigger probability of failure for soil material will occur.

Abstract

A disaster is an incident which threatens and disrupts life. This research was purposed to determine the critical slope stability in Bendosari Village, Pujon due to rainwater infiltration. This research was conducted through ground laboratory test to investigate the type and characteristic of the soil, which then followed by testing of the geo-electric and topography to investigate the existing condition and the ground water level on the critical slopes and analyzed safety factor (SF) using SLOPE/ W for slope with rainwater infiltration effect. The analysis results proved that rainwater infiltration in both conditions could reduce the SF (Safety Factor) value. This is because the water content in the soil increased the pore water pressure. In addition, high water content in the soil reduced the soil shear strength

Abstract

Geological structures and discontinuities in the rock are weak areas and groundwater infiltration pathways. The existence of geological structures and discontinuities will reduce the level of rock shear strength and the main implication is to increase the chance of landslides. The purpose of this study was to determine the type of sliding on rock slopes, rock mass classification, and to determine the stability of the rock slopes. Kinematic analysis obtained landslide type, rock mass classification analysis including medium rock mass class with an RMR value of 53. Slope stability analysis based on the generalized criteria Hoek & Brown failure obtained a safety factor value of 1.55 with a slope angle of 60°. Slope stability analysis based on Mohr-Coulomb criteria obtained a safety factor value of 1.59 with a slope angle of 70°.
