RISStress-Displacement Response of Sand–Geosynthetic Interfaces under Different Volume Change Boundary Conditions
Publisher: ASCE
Abstract: Volume change boundary conditions might dictate significant changes in normal stress and, accordingly, dramatically affect the stress-displacement response of soil-structure interfaces. Using a Norwegian Geotechnical ...
A Bioinspired Self-Burrowing Probe in Shallow Granular Materials
Publisher: ASCE
Abstract: Bioinspired strategies have been used in recent years to solve engineering problems in geotechnics. Inspired by the dual-anchor locomotion mechanism of razor clams, researchers are developing a new generation of self-burrowing ...
Field Evaluation of the Installation and Pullout of Snakeskin-Inspired Anchorage Elements
Publisher: American Society of Civil Engineers
Abstract: Soil nails and tieback anchors are used extensively for excavation support and slope stabilization; however, their performance can be complicated by limited pullout capacity or installation challenges. This paper presents ...
Monotonic and Cyclic Frictional Resistance Directionality in Snakeskin-Inspired Surfaces and Piles
Publisher: ASCE
Abstract: Interface friction is a governing parameter in the performance of piled foundations and other applications. Piles and other foundation elements typically mobilize a similar interface friction angle during loading in tension ...
Bioinspiration for Anisotropic Load Transfer at Soil–Structure Interfaces
Publisher: American Society of Civil Engineers
Abstract: Load transfer across soil–structure interfaces plays an important role in the capacity and efficiency of many geotechnical applications. Some geotechnical applications may benefit from soil–structure interfaces that mobilize ...
Load Transfer Directionality of Snakeskin-Inspired Piles during Installation and Pullout in Sands
Publisher: ASCE
Abstract: Deep foundation applications, such as foundations for jacket structures and reaction piles, may benefit from larger shaft resistances during tensile compared with compressive loading. A suitable analog for designing surfaces ...
Effect of Gradation on the Strength and Stress-Dilation Behavior of Coarse-Grained Soils in Drained and Undrained Triaxial Compression
Publisher: American Society of Civil Engineers
Abstract: Geotechnical engineering practice commonly estimates the properties and behavior of well-graded soils using methods and relationships developed based on the behavior of clean, poorly graded coarse-grained soils. The influence ...
Grain-Scale Tensile and Shear Strengths of Glass Beads Cemented by MICP
Publisher: ASCE
Abstract: This study explores the mechanical behavior of glass bead pairs cemented by microbial induced calcite precipitation (MICP) when subjected to tensile or shear loading. The mineral precipitation habit and contact area are ...
DEM Investigation of the Effect of Gradation on the Strength, Dilatancy, and Fabric Evolution of Coarse-Grained Soils
Publisher: American Society of Civil Engineers
Abstract: Design of geosystems built on coarse-grained soils with broader gradations are typically based on methodologies developed for clean sands without explicit consideration of the effects of gradation, potentially leading to ...
