An X-Ray CT Study on Transitional Internal Erosion under Triaxial Shearing
Publisher: American Society of Civil Engineers
Abstract: Internal erosion poses a significant threat to many geotechnical infrastructures as fine particles removed from gap-graded soils, which can be promoted by mechanical disturbances caused by human activities and natural ...
DEM Simulation of Creep in One-Dimensional Compression of Crushable Sand
Publisher: American Society of Civil Engineers
Abstract: Particle-scale mechanisms that control the static creep behavior of crushable sands are not well understood. In this context, this study examines the problem of creep of crushable sands undergoing one-dimensional (1D) ...
Effect of Frozen Ground on Seismic Response of Pile-Supported Bridge
Publisher: ASCE
Abstract: With the rapid development of China’s economy, the linear traffic infrastructure in the permafrost region has also developed rapidly. Many engineering problems in pile-supported bridges are caused by the freeze–thaw cycles ...
Modeling a Flexible Membrane for Triaxial Tests with Coupled FDM–DEM: Considering Realistic Particle Shape Effects
Publisher: American Society of Civil Engineers
Abstract: Particle morphology plays a crucial role in determining the mechanical behavior of granular materials. This paper focused on investigating the effects of boundary conditions on the triaxial mechanical properties of soil ...
Fracturing Behavior of Fine-Grained Soil Mixtures under Uniaxial Compression Studied Using X-Ray Microtomography
Publisher: American Society of Civil Engineers
Abstract: The micromechanical behavior of two fine-grained soil mixtures, i.e., RS-C containing river sand grains and GB-C containing glass beads, was investigated using X-ray microtomography (µCT). The specimens were uniaxially ...
DEM Analysis of Geomechanical Properties of Cemented Methane Hydrate–Bearing Soils at Different Temperatures and Pressures
Publisher: American Society of Civil Engineers
Anisotropy-Based Failure Criterion for Interphase Systems
Publisher: American Society of Civil Engineers
Abstract: This paper presents a methodology for estimating the shear strength of interphase systems composed of granular materials and planar inclusions having various degrees of roughness. Existing empirical and semiempirical ...
Construction of Urban Flooding Prevention System under “One City, One Executor, and One Network” Model: Case Study of Kunming, China
Publisher: ASCE
Abstract: Flood disasters have plagued developing countries and impeded sustainable city development as a result of global climate change and economic development. Chaotic urban flooding prevention system management is the current ...
