The presented work extends the state-of-the-art in scientific simulation-driven 3D construction process visualization. We present a tool, ParticleWorks that engineers can use to visualize construction processes involving “fuzzy”, unstructured, materials that are generally capable of flowing. Common processes that involve such fuzzy materials include placing concrete, dumping dirt, shotcreting, ...

The article assesses the impact of repeated blasts on stress-strain state shotcreting support, which negatively affects bearing capacity support and can lead to formation local rock falls in places significant degradation strength. Despite fact that a single seismic load usually does not have technical condition dynamic loading development negative processes affect safety. considers unreinforce...

Aiming at solving the problem of asymmetric deformation, failure, and stability control surrounding rock caused by excavation deep super large section soft chamber group passing through multilayer strata, taking connected vertical shaft in Wuyang Coal Mine as engineering background, deformation development mode rock, expansion situation loosening range, plastic failure response characteristics ...

This paper presents an experimental study on the fundamental performances of a sprayed engineered cementitious composite (ECC) in repair systems. ECC serving as a repair material has been expected to be highly effective in providing durable repaired structures because of the tight crack width control and high delamination resistance. For this study, a polyvinyl alcohol (PVA) fiber-reinforced EC...
