RISAlkali-Activated Ground-Granulated Blast Furnace Slag for Stabilization of Marine Soft Clay
Publisher: American Society of Civil Engineers
Abstract: This paper investigated the stabilization efficacy of alkali-activated ground-granulated blast furnace slag (GGBS) for a marine soft clay, compared with that of portland cement (PC). The influence of activators, including NaOH,
Reliability Analysis of Shield Tunnel Lining in Service with Field Inspection
Publisher: ASCE
Abstract: Under long-term service, shield tunnel linings are prone to diseases such as bolt corrosion, reinforcement corrosion, and cracks; therefore reliability analysis of tunnel linings is significant for overall tunnel stability. ...
Effect of Excavation Disturbance on Clayey Soil Mechanical Properties and Pile Capacity
Publisher: ASCE
Abstract: Excavation causes disturbance to the surrounding soil, affecting the soil’s mechanical properties. This study presents a case study to investigate the effect of excavation disturbance on soil properties and pile capacity ...
Study on Strength Characteristics and Hardening Mechanism of Alkali Residue–Based Lightweight Soil
Publisher: ASCE
Abstract: The accumulation of alkali residue has led to significant contamination of soil, air, and water, posing a hazardous threat to the environment. To address this issue, a technology and method for producing alkali residue–based ...
Experimental Study of Interface Shear Characteristics of Pervious Concrete and Carbonated Soil in the MgO-Carbonated Composite Pile
Publisher: ASCE
Abstract: Regarding a novel and low-carbon composite pile, the MgO-carbonated composite pile (MCP) is formed by a pervious concrete pile (inner core) at the center of a deep magnesia (MgO) mixing column (outer core) subjected to ...
Nonlinear Analyses for Coupled Problem of Temperature and Seepage Fields in Cold Regions Retaining Walls
Publisher: American Society of Civil Engineers
Abstract: In this paper, a mathematical mechanical model and the governing differential equations of the coupled problem of temperature and seepage fields, with phase change, are derived from the theories of heat transfer and seepage. ...
Comparison in Undrained Shear Strength between Undisturbed and Remolded Ariake Clays
Publisher: American Society of Civil Engineers
Abstract: Triaxial consolidation undrained shear tests are performed on both undisturbed and remolded Ariake clays to investigate the undrained shear strength behavior. When the applied confining stress is larger than the triaxial ...
Exploring Pore Structure Characteristics of Alkali Residue-Based Foamed Concrete and Their Effect on Compressive Properties: Insights from Low-Field Nuclear Magnetic Resonance Analysis
Publisher: American Society of Civil Engineers
Abstract: Based on investigated mechanical properties of alkali residue-based foamed concrete (A-FC), this paper presents a comprehensive examination of the microstructural features of A-FC and their impact on compressive properties. ...
Robust Geotechnical Design of Piles Incorporating System Reliability
Publisher: American Society of Civil Engineers
Abstract: There is a trade-off between pile safety and cost, and a balance between the two factors is crucial. An important aspect of pile safety that is often overlooked is design robustness, which requires that the structural ...
