One of the most effective parameters in economics of open-pit mines is the pit slope angle, so that the slope angle more than the optimum value increases the probability of a large failure in the pit wall and the slope angle less than the optimum value leads to increasing stripping ratio and reducing net present value of mine. Therefore, in this paper, considering the limit equilibrium methods ...

Two dimensional slope profile morphometric investigation in a part of the land failure prone Garhwal region of the Lesser Himalaya, Tehri district, U. P., India, indicates that the landslip morphology is closely related to the dominant movement processes active in this terrain. Technique developed for the morphometric analysis of landslips involves the use of five morphometric indices. Each ind...

Random finite element method (RFEM) provides a rigorous tool to incorporate spatial variability of soil properties into reliability analysis and risk assessment of slope stability. However, it suffers from a common criticism of requiring extensive computational efforts and a lack of efficiency, particularly at small probability levels (e.g., slope failure probability Pf<0.001). To address this ...

In slope engineering, soils are commonly at unsaturated state. The question of how to apply unsaturated soil mechanics theory to the slope stability analysis has become a hot spot in today’s geotechnical engineering research. Based on the experimental research of how shear strength of residual soil varies with water content, reasonable computation modules can be created. By using limit equilibr...

objectives the aim of this study was to investigate the relation between respiratory muscle strength and the severity of chf, and the influence of respiratory muscle strength on abnormal ventilation during exercise in chf patients. conclusions respiratory muscle strength is related to the severity of chf, and associated with rapid and shallow ventilation or excessive ventilation during exercise...

This research is conducted to develop the qualified data analysis system for predicting the behavior and failure of tunnel slope. The data from real-time monitoring system by CDMA communication is used to analyze the slope behavior. Tunnel slope shows different styles of behavior, because it is affected directly by temperature, rainfall and other weathering effects. In this paper, it is discuss...
