Quantifying the effect of brush layering on Slope stability
Ecological Engineering, 2010Co-Authors: Gian Battista Bischetti, Enrico Antonio Chiaradia, Vincenzo D'agostino, T. SimonatoAbstract:Soil bioengineering techniques that use vegetation as a structural element gained popularity in the field of natural and man-Made Slope stabilisation due to their ability to combine safety and environmental conservation elements. In spite of such popularity, little research has been done to quantify their effect on Slope stability. This work presents a simple scheme for the evaluation of the Factor of Safety for Slopes reinforced by brush layering, which is one of the most common techniques adopted in Slope stabilisation works. The proposed model is based on the limit equilibrium principle and accounts for geotechnical soil properties (cohesion, friction angle, unit weight of soil), soil saturation, Slope steepness, and brush layer design parameters (number of stems per meter, length and diameter of stems, distance between brush layers). The model provides the value of the Factor of Safety for a given Slope and soil depth. Laboratory pullout tests were carried out in order to estimate relevant parameters of cuttings of purple willow (Salix purpurea L.) and to perform a Slope stability analysis via the model.

Evaluation and Monitoring of Slope Stability in Cold Region: Case Study of Man-Made Slope at Øysand, Norway
'MDPI AG', 2020Co-Authors: Shin Yunsup, Choi, Jung Chan, Quinteros Santiago, Svendsen Ida, Heureux L Jean-sebastien, Seong JoohyunAbstract:Recently, the road and railways infrastructure developments in Norway have led to renewed interests on the geotechnical challenges associated with Slope stability under freezing-thawing cycles. Despite the amount of research available on the topic, there are few comprehensive studies involving laboratory testing, numerical analysis, and field monitoring of a Slope during a freezing–thawing. In this case study, a critical Slope was identified in a cold region based on field and laboratory tests, and a series of numerical simulations were carried out to evaluate the governing factor of Slope stability using finite element methods. A remote monitoring system was installed on a real scale man-Made Slope to observe its behavior against the governing factors of Slope stability. As a result, it was found that Slope stability at the critical Slope was significantly impacted by the freezing–thawing action, which was confirmed by the initial field observations from 2019 to 2020. Later, continuous monitoring data could be used to update soil parameters and to implement an early warning system for the high risky Slope areas effected by freezing–thawing action in many cold regions.publishedVersio

Effect of angle, length and circulation cooling system on microstructure A360 Aluminum alloy in semi-solid metal forming by cooling Slope method
Engineering Solid Mechanics, 2017Co-Authors: Mohammad Mahdi KaykhaAbstract:Article history: Received 6 July, 2016 Accepted 30 October 2016 Available online 31 October 2016 Application of cooling Slope in casting is a relatively simple process with low equipment and processing costs, which is able to produce semi-solid slurries with different parameters such as pouring temperature, length and angle of Slope plate, and plate type. In this study, the effect of angle and length of copper Made Slope plate on the microstructure of A360-Aluminum alloy is investigated. Microstructure study of metallographic samples in different conditions revealed that for 400mm Slope length and 60° Slope angle the optimum sphierized and homogenized microstructure is achieved. Also, under these conditions, the most hardness (77HB) was obtained, which might be because of suitable solidification conditions namely time and rate of shear stress. After finding the suitable conditions of Slope length and angle, the effect of the circulation cooling system was examined; and the method with cooling system was found to result in more homogenized microstructure compared to ordinary method. © 2017 Growing Science Ltd.
