“…The correlation results between SPT data and geophysical survey data are used in slope stability analysis and provide information about areas vulnerable to landslides triggered by earthquakes and other geological threats [7]. Marques et al (2017) conducted a slope stability study on a highway near Guarulhos City, Brazil. The study used the Morgenstern-Price analysis method to assess the slope stability of the highway at that location [8].…”

Landslide events cause road access to be cut off, such as in the Payung area of Batu City, which connects Malang and Kediri. Analysis and evaluation of landslide disasters need to be carried out in this area to anticipate the next landslides and reduce economic losses. This study aims to determine landslide potential in the Payung Area, Batu City, using the SPT method. The test is carried out at 2 points of the slope on the provincial roads and the slope above the road so that the two measurement points can be correlated. The data needed to analyze slope stability include the internal shear angle, cohesion, and soil unit weight; analysis and modeling of slope stability using Geostudio SLOPE/W software. The results of the slope stability analysis at point 1 show that the average failure line is at a depth of 6.00 m with the smallest Safety Factor (SF) value of 0.710 in scenario 2. While the slope at point 2, the failure line is at a depth of 1.50 m with the smallest FK value of 0.840 in scenario 2. Significant changes in the N-SPT value indicate differences in soil mechanical properties, such as shear angle and cohesion that affect the stability of the slope and cause landslides.

Evaluación del riesgo de deslizamientos superficiales para proyectos de infraestructura: caso de análisis en vereda El Cabuyal

et al. 2018

View full text Add to dashboard Cite

Este artículo presenta un análisis y evaluación cuantitativa de la amenaza, la vulnerabilidad y el riesgo asociados a deslizamientos superficiales en una subcuenca del Valle de Aburrá (Colombia). Se integra el modelo TRIGRS mediante una simulación de Montecarlo para la estimación de la probabilidad de falla en la subcuenca empleando una altura del nivel freático como factor desencadenante, que junto con su probabilidad de ocurrencia anual permiten la evaluación de la amenaza. Se emplea un modelo que cuantifica la vulnerabilidad física de estructuras basándose en la intensidad del deslizamiento y la resistencia del elemento expuesto. El riesgo anual se estima para una vivienda del sitio de estudio como el producto de la amenaza y el valor de la pérdida dado el evento catastrófico, considerando la vulnerabilidad. La metodología empleada se enfoca en el deslizamiento ocurrido el 26 de octubre de 2016 en un talud dentro del sitio de estudio que afectó la vivienda que es objeto de análisis.

Investigation on Deformation Mechanism and Treatment Effect of a Scattered Slope Based on Continuum–Discontinuum Element Method and Finite Difference Method

et al. 2022

Slope deformation and failure is an inevitable engineering problem in highway construction and operation in mountainous areas. Its essence is a continuous–discontinuous gradual failure process of slope under the action of unbalanced force. Slope deformation and failure mechanism is the basis and key content of its emergency treatment and comprehensive treatment. In this study, the continuous–discontinuous element method (CDEM) and finite difference method are used to analyze the deformation mechanism and support the effect of a scattered slope in the Biwei Expressway. The results showed that the change in the local geological environment caused by roadbed excavation leads to slope slippage along the surface and then pulls the upper rock mass gradually to produce slippage failure, resulting in the stability gradually decreasing. The mechanism is traction sliding–tensile cracking. The continuous–discontinuous element method can effectively simulate the formation process of the main and sub sliding planes during excavation and can better display the phenomenon of slope failure and gradual disintegration. The emergency disposal of the gravity anti-sliding retaining wall in front of the slope can effectively control further deformation and ensure temporary stability. In comprehensive treatment, step-type slope excavation, gravity anti-sliding retaining wall, and anchor frame beam are adopted to control the deformation and failure of slope and ensure long-term stability. The numerical simulation results are consistent with the actual results, which effectively explains the rationality of this study. The research results of this study can provide some reference for the emergency treatment and comprehensive treatment of slopes in mountainous areas and for the construction and operation of highways and other infrastructure in mountainous areas.
