Low-Pressure Polymer Immobilization Methods to Reduce Contaminant Leaching from Deep Vadose Zone Sands
(American Society of Civil Engineers, 2024)Water-reactive polymer grouts can be injected directly into contaminated sediment zones where a portion of the contaminated pore water may participate in grout polymerization and contaminants may be immobilized in the grout ... -
Deep Learning–Based Prediction of Tunnel Face Stability in Layered Soils Using Images of Random Fields
(American Society of Civil Engineers, 2024)The stability analysis of tunnel faces in multilayered soils presents challenges due to the inherent variability in natural soils. Although the random field finite-element methods offer a reliable approach to address such ... -
Geometrical Nonlinearities on the Bearing Capacity in Clay: A Validation Data Set for Numerical Tools
(American Society of Civil Engineers, 2024)A series of plate loading tests on clay has been conducted in the centrifuge. The aim of the tests is to create a data set, which is freely downloadable, to validate numerical tools that account for geometrical nonlinearities. ... -
Biocementation of a Well-Graded Gravelly Soil and Macromechanical Characterization
(American Society of Civil Engineers, 2024)Soil biocementation through microbially induced carbonate precipitation (MICP) is a promising technique for improving soil behavior in a nondisruptive manner, particularly for rehabilitation and retrofitting applications. ... -
Assessing Water Erosion Improvement in Beach Sand Treated with Bioslurry Using a Surface Percolation Technique
(American Society of Civil Engineers, 2024)Over the last 15 years, microbially induced calcite precipitation (MICP) has emerged as a possible solution to mitigate coastal erosion. To date, most MICP soil treatments that have been studied involve column injection ... -
Mobilized Shear Strength of Overconsolidated Seattle Clays
(American Society of Civil Engineers, 2024)The drained shear strength of overconsolidated glaciolacustrine clays in the Seattle area can range from the overconsolidated peak to residual strength depending on its geologic history, depth, softening, prior shear ... -
Performance Analysis of Shored Mechanically Stabilized Earth Walls with Wrapped Facing Using Numerical Simulations
(American Society of Civil Engineers, 2024)Although mechanically stabilized earth (MSE) walls typically require a reinforcement length-to-wall-height ratio of 0.7, the use of short reinforcement may be inevitable in certain situations, such as building MSE walls ... -
Experimental Study of Suffusion in Sand–Clay Mixtures under Variably Saturated Conditions
(American Society of Civil Engineers, 2024)Suffusion refers to the loss of small particles in a soil matrix without volume changes, caused by hydrodynamic forces and alternation of pore fluid chemistry. This study investigated the ionic concentration (IC)-induced ... -
Liquefaction Characteristics of Sand under Complex Seismic Loading Paths
(American Society of Civil Engineers, 2024)The effects of phase shift (δ) between compression and shear waves, and consolidation stress ratio (Kc) on the liquefaction resistance of sand under simultaneous compression and shear wave loading is investigated using a ... -
Centrifuge Modeling of Downward Soil Arching below Excavation Base in Dry Sand
(American Society of Civil Engineers, 2024)Excavation-induced soil arching is a key factor influencing the responses of the ground and underlying structures. This soil arching below an excavation base is defined as downward soil arching in comparison with that above ... -
Influence of Installation Method on the Axial Capacity of Piles in Very Dense Sand
(American Society of Civil Engineers, 2024)Three driven precast, four driven cast-in-situ, and four screw injection piles were installed and tested in dense to very dense sand at a site in the Netherlands. Each pile was instrumented with two types of fiber optic ... -
Axial Resistance of Pipelines with Enlarged Joints
(American Society of Civil Engineers, 2024)Buried pipelines subjected to permanent ground deformations (through, e.g., earthquake-induced liquefaction or fault rupture) often experience widespread damage. Regardless of the direction of ground movement, pipelines ... -
