ALL ABOUT CIVIL ENGINEERING
AbstractThe objective of this study was to investigate the content characteristics of heavy metals, metalloids, and nutrients in farmland soil in the entire Hunan Province, China. In addition, the spatial…
AbstractReal project experiences show that project actual risk cost is usually higher than expected. A significant reason for that overrun could be that the overall expected risk cost (ERc) is…
AbstractThe performance of retaining walls is affected by spatial variability in the properties of the retained backfill. In practice, the conventional approach for designing retaining walls is deterministic and is…
AbstractOne of the important issues in project management is cost contingency estimation. Although this has been investigated in previous studies, the underlying assumptions on presuming specific probability distribution functions (like…
AbstractThis study integrated reliability-based pavement performance prediction with scheduling of rehabilitation, considering the imperfect effect of repair. Traffic and pavement structural response data were collected from the national highways of…
AbstractA significant number of studies have found that the emissions, production, and expenses of earthmoving operations are dependent on numerous variables. However, there has been less evidence that has explored…
AbstractThe accuracy and efficiency of an approach using surrogate models are investigated, in comparison with traditional structural reliability methods, in the analysis of two steel structures subjected to natural fire.…
AbstractGeological heterogeneity is a result of the natural deposit process of strata with a highly irregular and uncertain distribution of soil mass in the real world. However, compared with the…
AbstractEvery year power outages affect millions of people. In the US, historical data show that between 2000 and 2016, 75% of outages (in terms of duration) were caused by severe…
AbstractTunnel roof deflection is an important measure to control the safety of excavation activity, especially for large-section tunnels using the sequential construction method. A three-dimensional (3D) model of a sequential…
