Interaction Model for Torsional Dynamic Response of Thin-Wall Pipe Piles Embedded in Both Vertically and Radially Inhomogeneous Soil
(ASCE, 10/1/2021)The inhomogeneity of soil is a ubiquitous problem for pile foundations due to, for example, pile installation (radial inhomogeneity) or the natural sedimentation of soil (vertical inhomogeneity). Most continuum theory ... -
Mechanism of Enzyme Stabilization for Expansive Soils Using Mechanical and Microstructural Investigation
(ASCE, 10/1/2021)Expansive soils are susceptible to ground movements and are problematic to overlying geotechnical structures. There is a growing shift to use nontraditional sustainable and economical alternatives. To date, limited research ... -
3D Discretized Rotational Failure Mechanism for Slope Stability Analysis
(ASCE, 11/1/2021)The kinematical approach of limit analysis has been historically employed to assess slope stability in the geotechnical community, for which most three-dimensional (3D) failure mechanisms are generally based on a composite ... -
Interpretation of Undrained Hollow Cylinder Shear on Natural Shanghai Soft Clay Using Three-Dimensional Constitutive Model
(ASCE, 10/1/2021)The mechanical response of natural clays can exhibit significant directional dependence due to loading history and layered soil structure. We report an experimental investigation of the stress–strain-strength response of ... -
ASS-GPR: Adaptive Sequential Sampling Method Based on Gaussian Process Regression for Reliability Analysis of Complex Geotechnical Engineering
(ASCE, 10/1/2021)Reliability analysis of complex geotechnical engineering is time-consuming since its performance function is highly nonlinear and implicit. In this paper, an adaptive sequential sampling metamodeling-based method is proposed ... -
