Prediction Models for Computation of Deformations and Interface Stresses in a Two-Layered Pavement Structure
Publisher: ASCE
Abstract: The granular layer, being the major structural component in low-volume roads, exhibits significant plasticity and undergoes both elastic and permanent deformation under repeated vehicular loading. Stress-dependent, nonlinear ...
Experimental Modeling for Time-Dependent Strength Behavior of Lignosulfonate-Treated High Plasticity Clay
Publisher: ASCE
Abstract: Traditional chemical stabilizers have been widely used for decades in order to enhance the strength and compressibility of soil. However, such stabilizers have been observed to create severe problems related to soil ...
Support Pressure for Stability of Horseshoe-Shaped Tunnels in Undrained Clay Using Lower-Bound Finite-Element Limit Analysis
Publisher: American Society of Civil Engineers
Abstract: In this paper, the peripheral stability of a horseshoe-shaped tunnel in undrained clay with linearly increasing and directionally dependent strength is studied using the lower-bound theorem of plastic analysis coupled with ...
Seismic Stability of Circular Tunnels in Anisotropic Granular Soil with Surcharge Loading Based on the Modified Pseudodynamic Approach
Publisher: ASCE
Abstract: This study evaluated the stability of circular tunnels constructed in anisotropic granular soil in the presence of surcharges on the ground surface and seismic loads. The stability problem was solved using the lower bound ...
Seismic Stability Analysis of Square and Rectangular Tunnels in Cohesive-Frictional Soils
Publisher: American Society of Civil Engineers
Abstract: Seismic activity on a tunnel damages the tunnel support systems. The extent of the tunnel damage depends on the soil type, the magnitude of the earthquake acceleration, and the tunnel cover depth. Hence, analyzing the ...
Seismic Active Earth Pressure of Granular Soils Considering Inhomogeneous Wave Velocities under Harmonic Excitation
Publisher: American Society of Civil Engineers
Abstract: Complete analytical solutions were developed for horizontal and vertical seismic accelerations considering wave velocities varying with depth as a generalized power-law function. This was done by enforcing the traction-free ...
Vertical Uplift Resistance of a Group of Two Coaxial Anchors in Clay
Publisher: American Society of Civil Engineers
Abstract: The vertical uplift resistance for a group of two horizontal coaxial rigid strip anchors embedded in clay under undrained condition has been determined by using the upper bound theorem of limit analysis in combination with ...
Seismic Passive Resistance of Cohesive-Frictional Soil Medium: Kinematic Limit Analysis
Publisher: American Society of Civil Engineers
Abstract: In the present study, extensive theoretical solutions in the form of charts have been generated based on a kinematically admissible translational mechanism for computing the passive resistance of cohesive-frictional soil ...
Discussion of “Seismic Uplift Capacity of Horizontal Strip Anchors Using a Modified Pseudodynamic Approach” by Anindya Pain, Deepankar Choudhury, and S. K. Bhattacharyya
Publisher: American Society of Civil Engineers
Upper Bound Solution for Pullout Capacity of Vertical Anchors in Sand Using Finite Elements and Limit Analysis
Publisher: American Society of Civil Engineers
Abstract: The horizontal pullout capacity of vertical anchors embedded in sand has been determined by using an upper bound theorem of the limit analysis in combination with finite elements. The numerical results are presented in ...
