Accurate and reliable predictions of rock deformations are crucial in many rock-based
projects in civil and mining engineering. In this research, a new system for the prediction of …

Backbreak is a rock fracture problem that exceeds the limits of the last row of holes in an
explosion operation. Excessive backbreak increases operational costs and also poses a …

Supply chain network design (SCND) is one of the important, primary and strategic
decisions affecting competitive advantages and all other decisions in supply chain …

Desert sands in Iran, which usually contain small amounts of silt and sulfate, do not have
significant strength, and thus, are not suitable for foundations or road construction. This …

The mechanical responses of tunnels with stiff and yielding linings were predicted using an
analytical method. A theoretical model of a stiff lining-supported tunnel was established …

Rock mass deformation modulus (Em) is a key parameter that is needed to be determined
when designing surface or underground rock engineering constructions. It is not easy to …

Aiming at the shortcomings of the BP neural network in practical applications, such as easy
to fall into local extremum and slow convergence speed, we optimized the initial weights and …

Abstract 'Clogging'is a common issue encountered during tunnelling in clayey soils which
can impede tunnel excavation, cause unplanned downtimes and lead to significant …

One of the sub-disciplines of geo-engineering is rock engineering, which studies the
behavior of rocks against internal and external factors. Fuzzy theory can be used to solve …

The determination of subgrade/subsoil strength is one of the most important pavement
design factors in transportation engineering, particularly for railways, roadways, and airport …
