... Abstract This study aims to analyze the effects of soil-structure interaction (SSI) in a building with shallow foundations in rocky mass, located in the city of Caruaru, Pernambuco, Brazil, and that had their settlements monitored by means of field instrumentation in four stages of its...

... rocks of claystone, siltstone and sandstone from southern alberta, are presented and evaluated in this paper. These observations indicate that foundation rock discontinuities and shear zones experience considerable deformation and concurrent long term behavior, in response to excavations and reservoir...

... Abstract To assess the shear strength of a gravity dam foundation, international guidelines recommend to consider the joints as unbounded and to use the Mohr-Coulomb (M-C) criterion. According to these guidelines, an apparent cohesion value (C APP ) can be used for the M-C shear strength...

... in order to increase their bearing capacity and reduce deformability is connected to the need of construction buildings at sites composed of filled or loose soils. The first methods of improving the physical and mechanical properties of soils at the base of the foundations were rested on their compaction...

... to simulate the process of pile penetration, and studied the impact of new piling on the existing pile foundation. Nuo et al. (2018) used PFC2D to establish two-dimensional numerical models of cast-in-situ piles and driven piles respectively, and compared the bearing capacity of two different types of piles...

... measures are not considered. Since road cutting at slope toe is often practicised for road widening, combined activities of building construction on the slope crest and slope undercutting may generate slip of rock mass beneath foundation. This requires an in-depth study on maximum allowable bearing...

At present, the concrete arch dam construction has been completed and preliminarily impounded, most of the foundation treatments have been implemented, and four of six generator units had been put into operation in July 2014. In this paper, the analytical methods, design...

... Abstract Type and shape of large dams founded on rock depend upon the expected deformation of their foundation. Their design consequently requires the assessment of the deformability of the rock mass at large scale. Seismic refraction, laboratory tests on rock samples and empirical formulas...

... Abstract Impounding deformation of slope and foundation is significant during and post dam construction. Reservoir impoundment is accompanied with various phenomena, including material degradation, effective stress decreasing and buoyancy in rock masses. These phenomena are related with some...

... Abstract Large subhorizontal joints have been found in the foundation excavations in basalt and granite of Brazilian Dams. Some spread for hundreds of square meters showed slickensides—polished surfaces plus striations—and laminations interpreted as related to shear displacement, what...

In this study, a discrete element modeling was performed in order to represent a transversely isotropic rock such as shale, and the upscaled model was applied to foundation and borehole problems using PFC2D. The applicability of the upscaled rock mass model was verified...
