RISComparison of Antistripping Performance Evaluation Methods on Asphalt Runway Pavement in Cold Regions
Publisher: American Society of Civil Engineers
Abstract: Influenced by aircraft engine wake effects, aggregates stripped off from asphalt runway surfaces are more severe during winter than during the other seasons in cold regions. In this study, five types of asphalt specimens ...
The Tensile–Shear Behavior of Loess and the Mechanism of the Tensile Strength Measured by the Unconfined Penetration Test
Publisher: American Society of Civil Engineers
Abstract: The tensile strength is an important parameter in engineering. Many engineering-related problems in buildings as well as the damage caused to them during natural disasters occur owing to a lack of tensile strength. The ...
Nonlinear Thermal Analysis for Qing-Tibet Railway Embankments in Cold Regions
Publisher: American Society of Civil Engineers
Abstract: Heat convection in ballast mass in railway embankments is a problem of heat convection in porous media. In order to calculate the temperature distribution of the Qing-Tibet railway embankment from the governing equations ...
Experimental Study on the Ventiduct Embankment in Permafrost Regions of the Qinghai-Tibet Railroad
Publisher: American Society of Civil Engineers
Abstract: This technical note presents an experimental study on the ventiduct embankment in permafrost regions of the Qinghai-Tibet Railroad. Two experiments were conducted in a test box and they were designed with similarity theory. ...
Numerical Investigation of the Temperature Field of a New Convection-Intensifying Composite Embankment in Permafrost Regions
Publisher: American Society of Civil Engineers
Abstract: One of the main problems of wide expressway construction in permafrost regions involves protection of the thermal stability of roadbed. Although ventilating ducts and crushed-rock layers have been successfully used in ...
Keying Behaviors of Strip Plate Anchors with Padeye Offset in Uniform Clay
Publisher: ASCE
Abstract: Plate anchors have great advantages that are useful in deep or ultradeep water mooring systems. The keying behaviors have a deep effect on the embedment loss and pullout capacity of strip plate anchors. In this paper, the ...
Bearing Capacity of Hybrid Skirted Foundations in Silty Sand-over-Clay under Combined VHM Loading
Publisher: American Society of Civil Engineers
Abstract: Hybrid skirted foundations have remarkably catered to the escalating demands in larger load-bearing capacity of offshore wind turbines due to its outstanding horizontal load resistance capacity and cost-effectiveness in ...
Cooling Effect of Two-Phase Closed Thermosyphons on a Cast-In-Place Pile Foundation in a Permafrost Region
Publisher: American Society of Civil Engineers
Abstract: A cast-in-place pile foundation, widely utilized in the permafrost regions of the Qinghai–Tibet Plateau, boasts superior load-bearing capacity, effectively mitigating the seasonal freeze–thaw effects. In permafrost regions, ...
Frost Jacking Characteristics of Transmission Tower Pile Foundations with and without Thermosyphons in Permafrost Regions of Qinghai–Tibet Plateau
Publisher: ASCE
Abstract: Frost jacking of electricity transmission tower (ETT) pile foundations in permafrost regions of the Qinghai–Tibet Plateau is becoming increasingly serious. This study investigated the effects of thermosyphons on the frost ...
