Influence of Deep Foundation Pits Excavation Construction of Newly-built Metro Stations on Adjacent Existing Operating Station in Soft Soil Strata

Chengshi guidao jiaotong yanjiu
ObjectiveSoft soil strata generally exhibit unfavorable engineering properties, such as low strength, high moisture content, significant compressibility, and uneven stratum distribution, showing complex stress-deformation behaviors. These characteristics

Experimental and smoothed particle hydrodynamics‐finite element method simulation investigation of synergistic erosion mechanism of gangue‐based abrasive water jets

Deep Underground Science and Engineering, EarlyView.
This study proposes an eco‐friendly coal permeability enhancement technique by utilizing mine waste gangue as an abrasive in high‐pressure water jets. Integrating erosion experiments with smoothed particle hydrodynamics‐finite element method coupled simulations, the research study elucidates the flow field dynamics and a nonlinear solid–liquid ...

Quiet activism as feminist practice

Feminist Anthropology, EarlyView.
Abstract In this article, we discuss how women combat silencing in the face of violence and increased political turmoil through quiet activism in their day‐to‐day lives. Centering lengthy conversations with Arab women across London and notes from an ongoing collaboration with a feminist activist based in the US, we examine how wearable rhetorical ...

Spontaneous hemoperitoneum in a 29‐week pregnancy with a history of endometriosis: A case report and review of the literature

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 31-37, April 2025.
Abstract Spontaneous hemoperitoneum in pregnancy (SHIP) is defined as sudden, nontraumatic intraperitoneal bleeding that occurs during pregnancy or up to 42 days postpartum. The incidence ranges between 4 and 4.9 per 100 000 births. Although seen rarely, it is associated with perinatal morbidity and mortality due to maternal hemodynamic instability ...

Optimising Sulphur Fertilisation in Ryegrass–White Clover Swards Reduces Leached Nitrate Nitrogen Losses, While Increasing Plant Yield and Nitrogen Off‐Take

Journal of Plant Nutrition and Soil Science, EarlyView.
The inclusion of sulphur at two inorganic nitrogen rates (0 and 150 kg N ha−1) improves plant productivity in a ryegrass–white clover sward and reduces nitrate‐N loss to groundwater in a free‐draining sandy loam soil. ABSTRACT Background Reducing nitrogen (N) losses to water, lessening reliance on inorganic fertiliser and maintaining agricultural ...

Numerical Simulation of Double-row Piles in Deep Foundation Pit Excavation

Journal of Physics: Conference Series
Abstract This paper aims to investigate the stress and deformation characteristics of double-row piles in deep foundation pit excavation by selecting representative strata in the Changchun area. The changes in bending moment, displacement, and earth pressure of double-row piles during the excavation are established using the FALC 3D ...

Ostracod faunal and geochemical evidence for the impact of Hoxnian (MIS 11c) sea levels in eastern England

Journal of Quaternary Science, EarlyView.
ABSTRACT Marine isotope substage 11c (~426–366 ka) is widely regarded as the most recent Pleistocene interglacial that is broadly analogous to the Holocene. The timing and magnitude of sea‐level changes during MIS 11 have been much debated, particularly concerning whether sea levels were significantly higher than during the Holocene. Empirical evidence

Impact of Deep Foundation Pit Covered-excavation Reverse Construction in Water-rich Sand Layers on Surrounding Environment

Chengshi guidao jiaotong yanjiu
［Objective］With the continuous advancement of urban modernization in China, the available space within cities is becoming increasingly scarce. Deep foundation pits are often constructed in environmentally sensitive areas, inevitably making impact on the ...
