RISFailure Mechanisms of Boreholes in Soft Coal Seams: Comparative Analysis of Protective Sieve Pipes
Publisher: American Society of Civil Engineers
Abstract: A key strategy for mitigating gas-related disasters involves the effective drainage of gas through in-seam short boreholes. Maintaining the integrity of these boreholes in soft coal seams, prone to deformation, collapse, ...
Influence of Coolant Density on Turbine Blade Platform Film-Cooling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Detailed parametric study of film-cooling effectiveness was carried out on a turbine blade platform of a five-blade linear cascade. The parameters chosen were freestream turbulence intensity, ...
Behavior of Large Bored Piles in Fuzhou
Publisher: American Society of Civil Engineers
Abstract: Large bored piles are popularly used in south‐east coast of China. Pile foundation design is based largely on empirical method. However, the behavior of these piles is not well understood. Generally, end bearing capacity ...
Unraveling the Progressive Failure Behaviors and Mechanisms of the Slope with a Local Dynamic Method Based on the Double Strength Reduction
Publisher: ASCE
Abstract: The cohesion c and the internal friction angle φ are mobilized at different reduction proportions and attenuation rates when a slope is in progressive failure, which is a dynamic development process. For this reason, an ...
Numerical Simulation of Desiccation Cracking in Clayey Soil Using a Multifield Coupling Discrete-Element Model
Publisher: ASCE
Abstract: Desiccation cracking in clayey soil, which may lead to soil erosion, geotechnical engineering accidents, or even environmental pollution, is a serious problem nowadays. This research proposed a multifield coupling ...
Influence of Coolant Density on Turbine Blade Film-Cooling Using Pressure Sensitive Paint Technique
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Adiabatic film-cooling effectiveness is examined on a high-pressure turbine blade by varying three critical engine parameters, viz., coolant blowing ratio, coolant-to-mainstream density ratio, and ...
Experimental Investigation of the Desiccation Cracking Behavior of Soil Layers during Drying
Publisher: American Society of Civil Engineers
Abstract: Desiccation cracking in drying soil is a common natural phenomenon, and it significantly impacts the soil’s mechanical and hydraulic behavior. In this study, experimental desiccation tests were conducted on an initially ...
Comparative Study on Perception of Causes for Construction Task Delay in China and the United States
Publisher: ASCE
Abstract: Rapidly growing construction markets in China and the United States have provided opportunities for contractors to venture into foreign industries. To help project managers understand the fundamental difference in culture ...
Soil Arching Effect Associated with Ground Movement and Stress Transfer Adjacent to Braced Excavation in Clayey Ground
Publisher: ASCE
Abstract: A field test for investigating the soil arching effect behind the diaphragm wall was carried out in an average 17-meter-deep, braced excavation in the normally-consolidated clayey ground. Horizontal and vertical ground ...
How Does Experience with Delay Shape Managers’ Making-Do Decision: Random Forest Approach
Publisher: ASCE
Abstract: Making-do, a decision to start a construction task despite knowing that its preconditions are not fully ready, is a complex dilemma for construction managers. Managers’ previous making-do decisions and the resulting ...
