Nowadays, underground structures play vital role in developing different countries. Such structures are constructed in many civil activities such as development of road and railways, subways, water, gas and sewage lines, underground subways, nuclear wastes land filling, fuel storage and military installations. With an appropriate drilling method being selected, instabilities created in tunnels ...

Large-scale molecular dynamics simulation is performed to study the nano-cutting process of single crystal copper realized by single-point diamond cutting tool in this paper. The centro-symmetry parameter is adopted to characterize the subsurface deformed layers and the distribution and evolution of the subsurface defect structures. Three-dimensional visualization and measurement technology are...

it more susceptible to leaching (Albus and Knighton, 1998). Higher moisture contents will also raise microbial Groundwater and surface water are significant resources for rural activity including mineralization (Skopp et al., 1990). water supplies, and certain agricultural practices may have substantial effects on these resources. An 11-yr study was started in 1989 near The increase in minerali...

Among the 19 segments of Great Sumatran Fault (GSF), Sianok segment is unique due to its proximity active volcanoes as well sizable Maninjau Caldera. Located next Sumani southeast, also passes through a relatively densely populated area. To identify potential disasters in future, it imperative understand subsurface structures segment. In this study, ground magnetic measurements were conducted, ...

Abstract Urban areas are major contributors to the alteration of local atmospheric and groundwater environment. The impact such changes on thermal regime is documented worldwide by elevated temperature in city centers with respect surrounding rural areas. This study investigates subsurface urban heat island (SUHI) aquifers beneath Milan area northern Italy, assesses natural anthropogenic contro...
