Fragility Analysis Presentation

Nov 29,20

We are pleased to announce that Dr. Zamiran will present a lecture in fragility and earthquake analysis of retaining walls at the 5th Annual Live Streaming Web Conference of Geo-Institute. In this investigation, the seismic response of retaining walls constructed with cohesive and cohesionless backfill materials was studied. Fully dynamic analysis based on the finite difference method was used to
evaluate the performance of retaining walls during different earthquake events. The analysis response was verified by the experimental study conducted on a retaining wall system with cohesive backfill material in the
literature. The effects of cohesion and free-field peak ground acceleration (PGA) on seismic earth thrust, the point of action of earth thrust, and maximum wall moment during the earthquake were compared with analytical and experimental solutions. The motion characteristics of the retaining wall during the earthquake were also considered. The relative displacement of the walls with various backfill cohesion, under different ground motions, and free-field PGAs were investigated. Current analytical and empirical correlations developed based on Newmark sliding block method for estimating retaining wall movement during earthquakes were compared with the numerical approach. Based on the developed model, fragility analyses were conducted to determine the probability of damage to the retaining walls during an earthquake event. Multiple earthquake ground motions were used to investigate the fragility response of the retaining walls. To evaluate the fragility of the studied model, a specific failure criterion was chosen for retaining walls. The failure criterion was selected based on different case histories of retaining wall failures and damages. It is demonstrated to what extent a small amount of cohesion in backfill material can influence the displacement of a retaining wall and the probability of damage in seismic conditions. According to the findings, practical correlations were presented for conducting the seismic design of retaining walls.

Stanford Earth Postdoctoral Fellowship Program

Nov 28,20

The Stanford Earth Postdoctoral Fellowship Program, introduced in 2020, represents a new step in diversifying the academic pipeline in the geosciences. We deeply appreciate the value of a diverse, equitable, and inclusive community, and we define diversity broadly to include diversity of genders, races and ethnicities, cultures, physical and learning differences, sexual orientations and identities, veteran status, and work and life experiences. The fellowship is funded by the Morton K. Blaustein Visiting Faculty Fund. As part of advancing Stanford University’s IDEAL vision and commitment to diversity (broadly defined) among its faculty, students, and staff, the School of Earth, Energy, and Environmental Sciences at Stanford University (Stanford Earth) has established the Stanford Earth Postdoctoral Fellows program. This fellowship will support two outstanding scholars in the fields of Earth, energy, and environmental sciences, as well as other emerging fields in this area, whose research and mentorship of undergraduate and graduate students will contribute to diversity, equity, inclusion and scientific excellence within the school.

Geomechanical Considerations of Anisotropic Behavior of Shale Layers

Jul 16,20

One of the major reserves of hydrocarbon explorations is shale reservoirs with unconventional geomechanical characteristics. The vast energy capacity of the mentioned reservoirs has led them to become one of the major targets of investment by the oil industry. However, due to the unconventional behavior of these reservoirs including anisotropic elastoplastic characteristics of shale layers and low permeability of the medium, traditional drilling methods do not lead to an appropriate strategy of oil extraction. On the other hand, a rigorous drilling method for operation of an oil field requires a precise comprehension of the geomechanical behavior of shale layers. The substantial aspects of geomechanical characteristics of shale layers include elastoplastic properties of the layers and stress and pore pressure distribution along the wellbore...
