(ASCE, 1/12/2023 )The effects of fines content on the liquefaction behavior and the dynamic response of gravelly soils were evaluated in this study. A total of six models of level-ground profiles of two saturated gravel-sand-fines mixtures ... -
Polymer Injection and Liquefaction-Induced Foundation Settlement Mitigation: A Shake Table Testing Investigation
(ASCE, 5/25/2023 )Shake table experiments are conducted to assess the potential of the polymer injection technique as a liquefaction countermeasure. A large 2.9 m high (10 ft) laminar soil container on a 3.9×1.85 m (13×6 ft) ... -
Various Bacterial Attachment Functions and Modeling of Biomass Distribution in MICP Implementations
(ASCE, 6/16/2023 )Microbial induced calcium carbonate precipitation (MICP) offers a robust technique to improve strength and stiffness properties of subsurface soils supporting infrastructures. Several unknown factors, including the MICP ... -
Centrifuge and Numerical Modeling of Liquefied Flow and Nonliquefied Slide Failures of Tailings Dams
(ASCE, 6/27/2023 )Tailings dams have relatively high failure rates throughout the world and the consequences of these failures often result in significant loss of life and damage to the environment and property. However, the triggers and ... -
Ventilated Well Method for Efficient Dewatering of Soft Soils: Dimensional Analysis and Validation through Numerical Modeling
(ASCE, 6/23/2023 )The ventilated well method (VWM) is a recently introduced novel dewatering and densification technique for soft soils that relies on controlled evaporation through ventilated and perforated wells traversing through the ... -
Relief Wells for Dams and Levees Considering Landward Head
(ASCE, 8/18/2023 )Relief well systems for dams and levees are often designed and analyzed as an infinite line using average and midwell heads. Well discharge and excess head in the foundation are calculated by adjusting the solution of a ... -
Effect of the Physical Characteristics of Sands on the Undrained Shear Behavior in the Steady State
(ASCE, 2/8/2023 1)The steady-state shear strength of sands is affected by the physical properties of the sand. If the correlation between physical properties of sands and their steady-state strength is known, the steady-state strength can ... -
Seismic Interactions among Multiple Structures Founded on Liquefiable Soils in a City Block
(ASCE, 7/10/2023 )Buildings are often located in close proximity to each other in urban settings. Seismic structure-soil-structure interaction near two adjacent buildings (SSSI2) on liquefiable soils has previously been investigated and ... -
Method for Estimating Fully Coupled Response of Deep Excavations in Soft Clays
(American Society of Civil Engineers, 2023/05/01)The influence of excavation rate, geometric layout, and hydraulic conductivity of basal and retained soils on the fully coupled solid–fluid behavior of braced excavations in cohesive soils is presented. Fully coupled ... -
Changes in Soil Properties over Time after a Wildfire and Implications to Slope Stability
(American Society of Civil Engineers, 2023/07/01)Postwildfire forests are dynamic environments. Wetting-induced shallow landslides are observed at varying times after wildfires, but the reasons are not fully known. This study investigates the time-dependent changes in ... -
