As a type of special geological body, soil-rock mixtures (SRMs) are widely found in nature and used civil engineering. Many structures, such as rockfill dams, highways tunnels, have SRMs building materials. Proper modeling is great importance to capture the complex behavior this heterogeneous material. In manuscript, simple constitutive model incorporating skeleton void ratio concept proposed f...

Settlement is one of the most important deformation characteristics of high concrete faced rockfill dams (CFRDs, >100 m). High CFRDs safety would pose a great threat to the security of people’s lives and property downstream if this kind of deformation were not to be measured correctly, as traditional monitoring approaches have limitations in terms of durability, coverage, and efficiency. It has...

Most of the existing studies on high dams under seismic action use stable ground motions, which cannot simulate non-stationary process practical motions well. Although many scholars have studied special characteristics motion frequency and intensity lately, relatively few systematic been carried out for residual deformation dam projects. In this paper, considering 144 stochastic acceleration ti...

The present study examined the effect of the geometric parameters of the Rockfill dams on the 2D static analysis of slope stability. In this regard, several numerical models analyzed for eight heights, three slopes of upstream and downstream, three vertical and skewed core thicknesses and four different impounding time stages namely, "End of Construction", "Full Reservoir", "Half Full Reservoir...

the mechanical behaviour of rockfill materials and aggregates depends not only on particle size and compaction, but also on their strength and lithological properties. in this research two types of large triaxial and direct shear tests are performed on rockfill materials. this paper compares the stress-strain behaviour of sandstone and andesibasalt materials in triaxial compression tests (3006...

construction of porous barriers to collect flood flows and gradual release of water, later, is one of the effective techniques for flood control. in this study, by carrying out a set of experiments in a flume with the width of 0.6, depth of 0.8, and length of 14 m, the effects of gradation of stones and downstream slope on the stability of such structures has been investigated. moreover, the in...

The configuration and safety factor of rockfill dams design depend on materials used in construction the dam. In some regions, available for using as impermeable element dam body are dispersive it is inevitable to consider dispersivity material construction. Internal erosion through cracks or other openings embankment most concern soils. authors have designed an by soil East Africa after finali...
