Limit Analysis for Local and Overall Stability of a Slurry Trench in Cohesive Soil
(American Society of Civil Engineers, 2015)This paper uses limit analysis to develop a two-dimensional (2D) and a three-dimensional (3D) analysis of slurry trench local and overall stability for cohesive soil. Formulas for the slurry trench stability analysis are ... -
Comparison of Anisotropic Rate-Dependent Models for Modeling Consolidation of Soft Clays
(American Society of Civil Engineers, 2015)Two recently proposed anisotropic rate-dependent models are used to simulate the consolidation behavior of two soft natural clays: Murro clay and Haarajoki clay. The rate-dependent constitutive models include the EVP-SCLAY1 ... -
Predicting Punchthrough of Jackup Spudcans on Sand over Clay
(American Society of Civil Engineers, 2013)This paper considers the prediction of spudcan punchthrough failure in sand over clay. Centrifuge model tests published in the literature reveal that the failure mechanism is complex and changes as the spudcan pushes through ... -
Three-Dimensional Analysis of Contaminant Migration through Saturated Homogeneous Soil Media Using FDM

Estimation of Maximum Pullout Shear Stress of Grouted Soil Nails Using Bayesian Probabilistic Approach
(American Society of Civil Engineers, 2013)The pullout resistance of soil nail is a key parameter in soil nailing design. Pullout resistance is affected by many factors, such as overburden pressure, grouting pressure, soil dilation, and degree of saturation of soil. ... -
New Pressuremeter Test Analysis Based on Critical State Mechanics
(American Society of Civil Engineers, 2013)To analyze the pressuremeter test results, the medium around the probe is modeled by a clay hollow cylinder subjected to external and internal uniform pressures. However, assuming that during the test the medium strains ... -
Effect of Deformation-Induced Suction in the Behavior of Unsaturated Fine-Grained Soils Using Simplified Finite-Element Model
(American Society of Civil Engineers, 2013)Matric suction is one of the important variables used to characterize the deformation behavior of unsaturated soil. The stress-strain relationship and the governing differential equations are the two elements in which ... -
Complete Stresses and Displacements in a Cross-Anisotropic Half-Space Caused by a Surface Vertical Point Load
(American Society of Civil Engineers, 2014)The elastic solution of a loaded cross-anisotropic half-space is dependent on the type of anisotropy that is governed by whether the characteristic equation has real and distinct or equal or complex roots. Most previous ... -
