An Improved Failure Model Considering the Arching Effect for Tunnel Face Stability in a Weak and Fractured Rock Mass
Publisher: ASCE
Abstract: Tunneling efforts that use shield machines often encounter weak and fractured rock formations, where the stability of the tunnel face is the principle safety control factor during tunnel construction operations. Within the ...
Analytical Model for Tunnel Face Stability in Composite Strata Considering the Arching Effect
Publisher: American Society of Civil Engineers
Abstract: During tunnel construction, the excavation face frequently encounters heterogenous weathered composite strata that considerably reduce tunnel face stability. To assess the stability of the tunnel face under such conditions, ...
Failure Behaviors of Oriented Strand Board Material under Quasi-Static and Dynamic Loads
Publisher: American Society of Civil Engineers
Abstract: Oriented strand board (OSB) is an engineering material used in the building industry. In lieu of its cost-effectiveness and sustainability, OSB has been used widely as the skin layer of structural insulated panel (SIP), ...
A Generalized Variational Method and Its Applications in Design of the Single-Jack Flexible Nozzle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nozzle facilities, which can generate high Mach number flows, are the core portions of the supersonic wind tunnel. Different from traditional fixed nozzles, a flexible nozzle can deform to designed contours and supply ...
A New Model for Isolating the Marine Heatwave Changes under Warming Scenarios
Publisher: American Meteorological Society
Abstract: Marine heatwaves (MHWs) exert devastating impacts on ecosystems. Understanding their responses to anthropogenic forcing has attracted rapidly growing scientific interest. Given the disparate adaptation capacity and mobility ...
