The creep parameters of rockfill materials obtained from engineering analogy method or indoor tests often cannot accurately reflect the long-term deformation high Concrete-Faced Rockfill Dams (CFRDs). This paper introduces an optimized inversion based on multi-population genetic algorithm-improved BP neural network and response surface (MPGA-BPNN RSM). used for are determined by parameter sensi...

The coefficient of earth pressure at rest, K0, is a significant mechanical parameter, and the investigation K0 coarse-grained soil has important theoretical significance applicational value in geotechnical engineering. However, there are few studies on influence initial dry density (ρd) due to limitations related test instruments or methods. A series tests for two types soils (rockfill sandy-gr...

Abstract There is a need of reducing the uncertainty in traffic loading-induced settlements within railway embankments. A previously developed model for unbound stone-based materials has been implemented modelling rockfill Particles were represented by simple breakable tetrahedral clumps spheres with four asperities each. Both corner breakage and particle splitting allowed. Embankments heights ...

The present paper considers aspects of underground iron ore mining in Ukraine, particular the level mine production and reserves basic fields. It analyzes generalizes practice using cemented rockfill under difficult hydrogeological conditions Pivdenno-Bilozerske high-grade field. Belozersky district is only one Ukraine that, without any technological cycle beneficiation, can provide both domest...

Discrete piles are used to stabilise infrastructure slopes, especially where there is insufficient additional land to allow construction of large toe berms or regrading of the slope. Compared with more conventional structures such as retaining walls, there are few field data on how discrete piles typically bend and displace under slope loading. This paper presents the results from monitoring a ...
