Liquefaction Resistance of Biocemented Loess Soil
(ASCE, 11/1/2021)Microbially induced calcite precipitation (MICP) is currently appraised to improve sandy soils, but only a few studies use it to solidify loess soil. MICP solidification tests and undrained cyclic triaxial tests were ... -
Analytical Model for Laterally Loaded Soil-Extended Pile Shaft Applied to Verifying the Applicability of Lateral PS Method
(ASCE, 10/1/2021)This paper investigates the dynamic response of soil around a laterally vibrating extended pile shaft and its application to the lateral parallel seismic (PS) integrity testing method. Considering the high pile to soil ... -
Hybrid Discrete-Continuum Approach to Model Hydromechanical Behavior of Soil during Desiccation
(ASCE, 10/1/2021)Desiccation cracking in clayey soils occurs when they lose moisture, leading to an increase in their compressibility and hydraulic conductivity and hence a significant reduction of soil strength. The prediction of desiccation ... -
Experimental Study on Seismic Instability of Pile-Supported Structure Considering Different Ground Conditions
(ASCE, 11/1/2021)The stability of pile-supported structures under earthquake loads involves complex dynamic soil–structure interaction (SSI). A series of large-scale shaking table experiments was performed to investigate the seismic ... -
Displacements, Strains, and Shear Bands in Deep and Shallow Penetration Processes
(ASCE, 11/1/2021)When penetrometers or probes are pushed into sand, complex displacement fields, strain fields, and shear band patterns develop. Deep and shallow penetration processes in sands generate substantially different patterns. ... -
Cyclic Degradation and Pore-Water Pressure Response of High-Plasticity Compacted Clay
(ASCE, 11/1/2021)This experimental study focused on cyclic degradation and cyclic pore-water pressure response of high-plasticity compacted clay under different dynamic loading and initial static shear stress conditions. The strain-controlled ... -
Piping Criteria for Hydraulically Stable Anisotropic Slopes
(ASCE, 11/1/2021)Piping has been a documented cause of collapse of multiple tailings dams, hydraulic structures and natural slopes. Important limitation of the existing piping criteria for a sloped ground is that they are treating soils ... -
Nonlinear Inelastic-Degrading Structural Modeling Approach to Assess the Seismic Soil–Structure Interaction Response of Tall Buildings
(ASCE, 10/1/2021)Oversimplifying structural modeling in the analysis of the seismic performance of tall buildings introduces variability and biases in the computed seismic response. Engineering demand parameters (EDPs) from coupled ... -
Tunneling-Induced Deformation of Bare Frame Structures on Sand: Numerical Study of Building Deformations
(ASCE, 11/1/2021)The paper compares the performance of two FEM approaches in reproducing the response of bare frame structures to tunneling in dry dense sand. A fully coupled approach, in which the tunnel, frame, and soil are accounted ... -
Modeling of Initial Stresses and Seepage for Large Deformation Finite-Element Simulation of Sensitive Clay Landslides
(ASCE, 11/1/2021)Groundwater seepage and an increased lateral earth pressure coefficient at rest (K0) increase the potential for triggering large-scale landslides in sensitive clays. After the failure is triggered, the successive retrogressive ... -
Numerical Study of Footprint Generation and Reinstallation of Jack-Up Footings
(ASCE, 10/1/2021)Jack-up leg installation, extraction, and reinstallation near extraction-induced footprints are simulated using the coupled Eulerian-Lagrangian method with a strain-softening soil model. A typical footprint considering ... -
Effect of Keying-Induced Soil Remolding on the Ultimate Pull-Out Capacity and Embedment Loss of Strip Anchors in Clay
(ASCE, 10/1/2021)In this paper, the keying of strip anchors in clay has been studied by employing a large deformation finite-element methodology coupled with a soil constitutive model that takes strain rate and soil remolding into ... -
