Pile foundation systems are used in India many projects such as metro and railways, flyovers, multi-story buildings. The pile transfers superstructure load to the substructure, i.e. rock layers by means of skin resistance end-bearing resistance. In this study, an attempt is made observe performance socketed piles soft rock. A series small-scale model laboratory studies have been conducted using...

The weakening effect is one of the most important causes triggering large deformation and failure soft-rock engineering; however, few studies paid attention to damage evolution constitutive relationship rock in tensile excavation unloading water-weakening process, not mention coupling process water-weakening. In this paper, mechanism engineering characteristics softening water-softening water-r...

in this study, the amount of nickel and vanadium elements in the soft tissues of rock oysters (saccostrea cuculata) and sea water from coastal areas of qeshm island, the biggest island of persian gulf located in the south of iran, were measured to evaluate the contamination of the aquatic environment and organisms. following the bioassay, weighing and chemical digestion of the samples, finally...

the main objective of this study is to swing krull intersection theorem in primary decomposition of rings and modules to the primary decomposition of soft rings and soft modules. to fulfill this aim several notions like soft prime ideals, soft maximal ideals, soft primary ideals, and soft radical ideals are introduced for a soft ring over a given unitary commutative ring. consequently, the p...
