Subway Station Accessibility and Its Impacts on the Spatial and Temporal Variations of Its Outbound Ridership
Publisher: ASCE
Abstract: Understanding the influencing factors of subway station outbound ridership provides sights into current subway system operations and future expansion needs. The accessibility of a subway station quantifies the potential ...
Numerical Investigation on Microcrack Propagation Behavior of Heterogeneous Rock under Ultrasonic Vibration Load
Publisher: American Society of Civil Engineers
Abstract: The use of ultrasonic technology for rock breaking, with its high-frequency and microamplitude impact load, is anticipated to help overcome the challenges of high economic cost and low rate of penetration in mineral resource ...
Characterization and Mechanism Analysis of Hydrophobic Polymer-Modified Saline Soil
Publisher: American Society of Civil Engineers
Abstract: Saline soil is composed of abundant soluble salts, exhibiting undesirable properties when used in backfill projects. To address the mentioned problem, a hydrophobic polymer with an active ingredient of hydrosiloxane-containing ...
Attenuation and Time-Frequency Characteristics of Explosion Ground Vibration of Shallow Buried OD1422-X80mm-12 MPa Pipeline Based on Prototype Experiment
Publisher: ASCE
Abstract: In this paper, the explosion experiment of OD1422-X80mm-12 MPa natural gas pipeline was carried out to study the vibration hazards. The classic Sodev’s empirical formula was improved to predict the vibration velocity ...
