The in situ block size of the rock mass may be the single most important parameter influencing the stability and strength of some underground openings. Rock masses can often reasonably be characterized by a simple size-strength classification. The actual block size distribution is the product of the interaction between the joint orientation, spacing and persistence of that rock mass. Despite th...

Like other large-scale development projects, the design, construction, and utilization of subway projects have several positive negative environmental consequences. In this study, geological hazards in construction phase Ahvaz Subway Line 1identified localized. The impacts also were assessed surface subsurface sections. During evaluation, after providing preparing required information layers, A...

Actualmente, existen pocos estudios que aplican métodos de simulación geoestadística para modelar las propiedades geomecánicas los macizos rocosos, y la mayoría estos pasan por alto anisotropía datos geotécnicos. Por lo tanto, el objetivo del presente estudio es desarrollar un modelo geotécnico en 3D mediante Kriging ordinario con ello, establecer parámetros geotécnicos empleados identificar zo...

In recent decades, the effects of blast loads on existing structures have gained considerable attention due to increase in threat from various activities. Site-specific empirical relationships for calculation blast-induced vibration parameters like Peak Particle Velocity (PPV), Acceleration (PPA), and Displacement (PPD) are commonly used estimation impact blasting an adjacent tunnel. However, th...
