Durability analysis and damage constitutive modeling of fiber-reinforced reactive powder concrete of drilling shaft in porous water-bearing rock stratum

open access: yesCase Studies in Construction Materials, 2023
The drilling activities at the mining sites in western China generally involve an extremely high drilling depth and complex formation environment, and the external load borne by the drilling shaft lining is also very high.

A Universal van der Waals Tunneling Injector for Monolayer CMOS

open access: yesAdvanced Materials, EarlyView.
A universal van der Waals injector unlocks polarity‐flexible tunneling contacts for monolayer CMOS. SnSe2, an intrinsically degenerate 2D semiconductor, establishes polarity‐specific band alignments with both WSe2 and MoS2 channels, enabling steep switching, high on/off ratios, and a unified route to low‐power 2D logic.

Experimental and Analytical Assessment of Shaft Resistance and Critical Depth of Piles Subjected to Uplift Loads in Overconsolidated Sand

open access: yesGeotechnics
Pile foundations are widely used to transfer axial loads to deeper strata, where uplift resistance is critical for offshore structures, towers, and retaining systems. Uplift capacity is governed primarily by shaft resistance mobilized along the pile–soil

Shaft Resistance of Long (Flexible) Piles Considering Strength Degradation

open access: yesJournal of Engineering, 2021
Soil-structure frictional resistance is an important parameter in the design of many foundation systems. The soil-structure interface area is responsible for load transferring from the structure to the surrounding soil.

An investigation of correlation factors linking footing resistance on sand with cone penetration test results [PDF]

open access: yes, 2012
Significant research effort has led to improvements in our ability to estimate the ultimate bearing resistance of footings in sand. These techniques often estimate the footing resistance at relatively large displacements, typically 10% of the footing ...

Measurement of Additional Strains in Shaft Lining Using Differential Resistance Sensing Technology

open access: yesInternational Journal of Distributed Sensor Networks, 2013
As is well known, shaft lining fracture is the main disaster resulting in a large amount of fatalities and property loss. Thus, the additional strain is a key parameter to evaluate the safety condition of existing shaft linings. In this study, a new type
