Analysis of Arch Forming Factors of Shallow Buried Hard Rock Tunnel under Overlying Load

Buildings, 2023
To investigate the arching effect of shallow buried hard rock tunnels under overlying load, the engineering scenario of a subway station on Qingdao Metro Line 6 is utilized. A large-scale tunnel loading model test is conducted, in conjunction with finite

Models of stress fluctuations in granular media

, 1997
We investigate in detail two models describing how stresses propagate and fluctuate in granular media. The first one is a scalar model where only the vertical component of the stress tensor is considered.

Calculation of Horizontal Bearing Capacity of Anti-Slide Piles Based on Soil Arching Effect and Improved Strain Wedge Model in Loess Sites

Shanghai Jiaotong Daxue xuebao
Landslide prevention and control is one of the prominent topics in the field of geological hazards. The passive soil arching effect, adjacent to the piles, is a key factor influencing the horizontal load-bearing capacity of anti-slide piles.

A Numerical Analysis on the Performance of Counterweight Balance on the Stability of Undercut Slopes [PDF]

International Journal of Mining and Geo-Engineering, 2017
One of the important parameters in undercut slopes design is the determination of the maximum stable undercut span. The maximum stable undercut span is a function of slope geometry, the strength parameters of the slope material, condition of ...

Capitalism’s Cynical Leviathan: Cynicism, Totalitarianism, and Hobbes in Modern Capitalist Regulation [PDF]

, 2008
In this paper I have tried to show the symbiotic relationship between discursive systems of totalitarianism and cynicism. Whether speaking of a social Leviathan a la Hobbes or localized capitalist regulation each relies upon the symbiotic combination of ...

The temporal trends and short‐ and long‐term mortality of people with acute myocardial infarction and rheumatoid arthritis: a nationwide cohort study

Arthritis Care &Research, Accepted Article.
Aims We investigated whether a diagnosis of rheumatoid arthritis (RA) affects the quality of inpatient acute myocardial infarction (AMI) care and long‐term mortality post‐AMI. Methods We analysed data from 784,091 adults, 6,047 with a diagnosis of RA, from England and Wales hospitalised with AMI between 2005 and 2019 from the MINAP registry, linked ...

Embankments Reinforced by Vertical Inclusions on Soft Soil: Numerical Study of Stress Redistribution

Geotechnics, 2023
Constructing embankments over soft soils is a challenge for geotechnical engineers due to large settlements. Among diverse ground-improvement methods, combining piles and geosynthetics (e.g., geosynthetic-reinforced piles, deep cement mixing columns ...
