RISQuantitative Study of the Action on Rock Mass Failure under the Shock Wave and Gas Pressure in Bench Blasting
Publisher: ASCE
Abstract: The expansion and shock wave coexisting failure theory has been widely recognized. However, it is not clear whether the main cause of rock mass blasting failure is the shock wave or gas pressure. In this paper, the ...
Nonlinear Effects of the Built Environment on Subways at Station Level: Average Travel Distance Changes under the Influence of COVID-19
Publisher: American Society of Civil Engineers
Abstract: The travel behavior of subway passengers has shown systematic differences with the onset and progression of the COVID-19 pandemic. This study focused on subway stations in Xi’an and systematically analyzed the spatiotemporal ...
A Quantitative Method for Predicting the Fragmentation Range in Rock Blasting Based on the Dynamic Coupling Effect of In Situ Stress and Explosive Load
Publisher: American Society of Civil Engineers
Abstract: The rock blasting crush zone and fracture zone develop in the direction of major principal stress under the influence of in situ stress. However, there is still a lack of an accurate calculation method for predicting the ...
Measuring the Relationship between Influence Factor and Urban Rail Transit Passenger Flow: Correlation or Causality?
Publisher: ASCE
Abstract: The analysis of factors influencing urban rail transit (URT) passenger flow is often a precondition for establishing prediction models. Much past analysis has focused on correlation analysis and does not draw on research ...
