Pre-stabilization of soft soils using high-modulus columns prior to bored pile construction: an innovative approach

open access: yesOpen Geosciences
The construction site of a silo, which was built as two sites, consists of very soft alluvial soils. Since the superstructure loads exceeded the bearing capacity of the shallow foundation, the structure was built on a deep foundation with bored piles ...

Fracture Development Mechanism of Water‐Isolating Soil Layers During Downward Mining of Shallow‐Buried Coal Seam Groups

open access: yesEnergy Science &Engineering, EarlyView.
This study systematically investigates the fracture development mechanisms of water‐isolating soil layers under the coupled effects of repeated mining and groundwater seepage during the downward mining of shallow‐buried coal seams. The findings provide a theoretical basis for evaluating stratum stability and preventing roof water inrush.

Post‐Stimulation Hydraulic Response and Productivity Constraints of a Low‐Productivity Carbonate Geothermal Well in the Small Intramontane Basin, Beijing Piedmont, North China

open access: yesEnergy Science &Engineering, EarlyView.
Formed ~1.4 Ga, the carbonate reservoir of the Jixian System is a key geothermal reservoir in northern China. Differential basin–mountain evolution since the Cenozoic led to distinct reservoir‐forming histories; consequently, this same reservoir shows marked productivity contrasts between intramontane basins and the large rift Bohai Bay Basin ...

Research on Wellbore Collapse of Stratification Formation

open access: yesShiyou jixie, 2019
The development micro-fractures, joints and bedding in the middle and deep strata of the Bohai Oilfield makes the collapse pressure predicted using conventional integrate formation not consistent with actual situation.

Research on stability mechanism of roadway roof under dynamic loading induced by blasting excavation

open access: yesMeikuang Anquan
Addressing the stability issues of the immediate roof in roadways caused by subsidence and vibration during blasting excavation, this study takes the high-level drainage roadway of Panel 3203 in Wangpo Coal Mine as the engineering background.

Determining the Optimal Water Storage Depth of Apple Orchards in the Chinese Loess Plateau: Balancing Soil Desiccation Mitigation, Plant Utilization, and Engineering Construction

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Deep‐rooted plantations are central to dryland ecological restoration, yet their long‐term cultivation drives widespread deep soil desiccation, threatening ecosystem sustainability. While artificial water replenishment is a key deep soil desiccation mitigation strategy, the depth‐dependent positional effect of stored water on eco‐hydrological ...

Corrosion of Potential Canister Materials During Oxic to Anoxic Transient in Compacted Bentonite

open access: yesMaterials and Corrosion, EarlyView.
A comprehensive analytical approach was applied to investigate material degradation phenomena of cast iron and copper as potential canister materials for the safe disposal of high‐level radioactive waste, as well as compacted bentonite exposed to artificial water relevant for disposal. ABSTRACT The long‐term performance of the engineered barrier system

Within‐tree spatial heterogeneity of sap flow velocities and wood properties and its effect on the uncertainty of tree level sap flux estimates

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
As forests are important for biodiversity and recreation and provide vital resources globally, it is essential that their health can be accurately monitored, for example, by using sap flow probes to measure tree water uptake. We investigated whether sap flow measurements might differ at various locations within the same tree due to variation in wood ...
