Mechanism and disaster control new technology of strong ground pressure manifestation in ultra‐large mining face

open access: yesDeep Underground Science and Engineering, EarlyView.
In response to the problem of strong mining pressure manifestation along the goaf roadway in a thick coal seam mining area, this study uses a new type of combined blasting roof cutting technology to effectively control the manifestation and deformation of mining pressure along the goaf roadway.

Issued as a Documentation Report on an Investigation of Field-Made Joints in Prestressed Reinforced Concrete Highway Girder Bridges, Project IHR-303, Phase 2 [PDF]

open access: yes, 1977
A prototype bridge girder was designed, built, and tested. The 250 ft long two-span girder was made of 3 precast segments about 88, 74, and 88 ft in length. The segments were supported on 3 final and 2 temporary supports.

Finite Element Modelling of Rocking and Hybrid Precast Walls under Seismic Loading

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT In recent years, self‐centring systems have received considerable research interest in the seismic design of precast concrete structures for their ability to limit damage and satisfy resilience requirements. Rocking and hybrid structural walls, characterised by the formation of a single gap at the wall–foundation interface, mitigate damage by ...

Comparing the rigidity of the prestressed and non-prestressed foundation [PDF]

open access: yes, 2016
If compared with reinforced concrete, the prestressed concrete is able to resist higher loads before cracks develop. As cracks reduce considerably rigidity of the element, the prestressed element can be regarded as rather rigid.

Full-scale testing and numerical analysis of a precast fibre reinforced self-compacting concrete slab pre-stressed with basalt fibre reinforced polymer bars [PDF]

open access: yes, 2017
open7Steel-free pre-stressed reinforced concrete may be used in aggressive environments to increase the durability of structural elements and to limit the carbon footprint by replacing steel with high-strength fibre composites.

Research on Optimal Width of Coal Pillars in Both Sides of Abandoned Mining Areas and Tunnel Control Technology

open access: yesEnergy Science &Engineering, EarlyView.
This study primarily investigates the optimal width for coal pillar retention in both sides of the worked‐out face section. Taking the 42201 haulage roadway of the 42201 working face at Shengxin Coal Mine as the primary research target, it analyses the optimum width for coal pillar retention through theoretical calculations, numerical simulations, and ...

POST-TENSIONED BOX GIRDER BRIDGE An Analysis Approach using Equivalent Loads [PDF]

open access: yes, 2016
Continuous-span, cast-in-place box girders have been popular in modern bridge construction. Secondary moments due to prestressing in continuous-span, post-tensioned girders, however, have significantly complicated the structural analysis and design of ...

Pre-stressed anchor cable force evolution laws of plane sliding bedding slopes

open access: yesInternational Journal of Geo-Engineering, 2023
This paper aims to understand how anchor cable force evolution laws can improve reinforcement designs. The self-developed weak plane sustained deterioration technology was conducted in the indoor test on the reinforced bedding rock slope containing a ...
