Strengthening of unstable embankments using geogrids of basalt fiber and reinforced bars

Вестник Научно-исследовательского института железнодорожного транспорта, 2016
The article deals with the problem of stability of embankments on a strong and a weak base. On the main field-site of roadbed composed of clay soils ballast depressions (troughs, beds) are distributed.

Optimizing Strategies for Non‐Invasive Prospection of Settlements in the Intertidal Zone: A Case Study From the Centre of the Drowned Medieval Village of Tolsende (Scheldt Estuary, the Netherlands)

Archaeological Prospection, EarlyView.
ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

Numerical research on anti‐dislocation measures design of deep‐buried tunnels in an anisotropic rock mass area

Deep Underground Science and Engineering, EarlyView.
This paper conducts a numerical simulation study on the construction of a deep‐buried tunnel in an anisotropic stratum area. A statistical analysis of the effects of two anti‐faulting design measures, namely, a conventional design and an articulated design, is carried out, and the results demonstrate the effectiveness of the anti‐faulting structures ...

Improvement in seismic resistance using replacement/counterweight fill method for existing high embankments on inclined ground constructed with various embankment materials

Soils and Foundations, 2023
The seismic resistance of existing embankments has become a significant issue as embankments fail frequently because of earthquakes. However, there are only a limited number of methods that can improve the seismicity of these existing embankments.

Mitigating surcharge‐induced column‐head cracking in double‐deck shield tunnels using hyperelastic bearing joints

Deep Underground Science and Engineering, EarlyView.
A staged three‐dimensional nonlinear soil–structure interaction (SSI) model is established, in which the initial geostress state, tunnel excavation, lining installation, delayed activation of the internal frame, and subsequent surcharge loading are simulated sequentially.

The matrilineal Turn: Wiradjuri matrilineal leadership, colonial disruption, and the work of cultural return

Feminist Anthropology, EarlyView.
Abstract This article advances three claims regarding the matrilineal organization of Wiradjuri society in central New South Wales. Drawing on the late nineteenth and early twentieth century ethnographic record, it demonstrates that Wiradjuri descent, totem, moiety identity, and ceremonial authority were and are matrilineally organized, despite ...

Use of Bottom Ash from a Thermal Power Plant and Lime to Improve Soils in Subgrades and Road Embankments

Applied Sciences
The present study has focused on stabilizing the soils of the embankments and improving the mechanical properties of gravel in subbases of pavements with different contents of bottom ash from thermal power plants and low percentages of lime. The density,

Viability analysis and the importance of fine‐scale variables influencing roadkills of a toad population

The Journal of Wildlife Management, EarlyView.
Fine‐scale population variables better explain roadkill patterns in natterjack toads (Epidalea calamita) than habitat proxies, with mortality driven mainly by local abundance, reduced by roadside embankments, and decreasing as the season advanced. Despite high roadkills, population viability analyses indicate no immediate extinction risk under current ...

Phytotoxicity Assessment of Ashes Generated From Household Combustion of Conventional Fuels, Mixed Fuels, and Municipal Waste

Land Degradation &Development, EarlyView.
ABSTRACT The main aim of the study was to assess the toxicity of ash generated in household furnaces through the combustion of materials most commonly burned in individual households. The toxicity tests were conducted using plant bioassays with cress (Lepidium sativum), mustard (Sinapis) and sorghum (Sorghum) seeds.
