Experimental and Theoretical Investigations on Evolution of Soil-Arching Effect in 2D Trapdoor Problem
Publisher: ASCE
Abstract: Soil arching effect has been widely recognized as one of the most critical factors governing load-transfer mechanism in the design of various geotechnical infrastructures. However, most existing studies on soil arching ...
Improved Vacuum Preloading Method Combined with Sand Sandwich Structure for Consolidation of Dredged Clay-Slurry Fill and Original Marine Soft Clay
Publisher: ASCE
Abstract: An improved vacuum preloading method combined with a sand sandwich structure (SSS) was developed to facilitate the consolidation of dredged clay-slurry fill and original soft marine clay for land reclamation. In this method, ...
New Technique for Ground Vibration Mitigation by Horizontally Buried Hollow Pipes
Publisher: ASCE
Abstract: Mitigating the ground vibration initiated by the passage of trains to safeguard the surrounding structures is a challenge for geotechnical engineers. Among various existing methods, open trenches are one of the most common ...
Laboratory Analyses of Noncoaxiality and Anisotropy of Spherical Granular Media under True Triaxial State
Publisher: ASCE
Abstract: Anisotropy of the soil is responsible for its noncoaxial response. In simple shear and hollow cylindrical torsional shear tests, considerable noncoaxial responses were detected as a result of the stress-induced anisotropy ...
Strength, Durability, Corrosion Resistance, and Microstructure of Cemented Soil Incorporating Nano-MgO under Static and Cyclic Loading: A Laboratory Study
Publisher: American Society of Civil Engineers
Abstract: Coastal regions often face challenges with the degradation of cementitious foundations that have endured prolonged exposure to corrosive ions and cyclic loading induced by environmental factors, such as typhoons, vehicular ...
Determination of Active Earth Pressure on Rigid Retaining Wall Considering Arching Effect in Cohesive Backfill Soil
Publisher: American Society of Civil Engineers
Abstract: A new simplified method is proposed to compute the active earth pressure acting on the backface of a rigid retaining wall undergoing horizontal translation. The effect of soil arching for cohesive backfill soil and friction ...
Estimation of Passive Earth Pressure against Rigid Retaining Wall Considering Arching Effect in Cohesive-Frictional Backfill under Translation Mode
Publisher: American Society of Civil Engineers
Abstract: In this study, a novel analytical approach is proposed to calculate the passive earth pressure against a rigid retaining wall subjected to the translation mode. Effects of arching in cohesive backfill soils as well as ...
Hybrid Approach for Rigid Piled-Raft Foundations Subjected to Coupled Loads in Layered Soils
Publisher: American Society of Civil Engineers
Abstract: This paper proposes an efficient hybrid approach for analysis of the responses of piled-raft foundations subjected to coupled loads (combination of vertical loads, horizontal loads, and moments) in layered soils. The ...
Biaxial Creep Test Study on the Influence of Structural Anisotropy on Rheological Behavior of Hard Rock
Publisher: American Society of Civil Engineers
Abstract: Rheological characteristics are one of most important properties needed to be considered in the design and construction for the long-term stability and serviceability of underground structures in the rock mass. To date, ...
Three-Dimensional Slope Stability Analysis Incorporating Coupled Effects of Pile Reinforcement and Reservoir Drawdown
Publisher: American Society of Civil Engineers
Abstract: In pile-reinforced dams and bank slopes, the antislide effect of piles and drawdown of reservoirs are two aspects that could significantly affect the slope stability. However, existing studies have incorporated these two ...
