The city of Beirut sits on a peninsula along Lebanon’s Mediterranean coast. The Port of Beirut, opened in 1887, is located directly north of downtown Beirut and mostly separated from the commercial and...

Automated Model And Parameter Selection: Incorporating Expert Input into Geotechnical Analyses
Excavation for construction of MIT Stata Center in Cambridge, MA. This complex soil-structure interaction problem required advanced numerical methods and soil constitutive models. A) PLAXIS 3D model of...

The Present And Future Of Virtual and Augmented Reality In Geotechnical Engineering: This Technology Has Gone Way Beyond Gaming!
One of the greatest challenges with subsurface construction has always been our relative inability to visualize underground conditions that are often comprised of spatially variable soil and rock strata,...

Reliability-Based Design (RBD) For Everyone: (No Monte Carlo Simulation Required!)
In North America, the design of earth structures for transportation applications is most often carried out using load and resistance factor design (LRFD). In the U.S., the AASHTO LRFD Bridge Design Specifications...

Photogrammetry for Rock Engineering: A Snapshot of State-of-the-Art Rock Mapping
Generally speaking, photogrammetry is the science of turning photographs into 3D models. While flashy advertisements may convey the idea that it's as simple as pushing a button (e.g., on a drone remote)...

What's New in Geo? The Future of Numerical Geo-Modeling: Is 3D Here to Stay?!
Application of soil mechanics in engineering practice has undergone remarkable changes over the past 50 years as a result of developments in computer technology. Each improvement in computing capability,...

Calibration of Jackup Leg Foundation Model Using Full-Scale Structural Measurements
The fitness of jack-up rigs to operate in varying water depths and weather conditions is determined by "site-specific" structural assessments. These assessments are conducted by a wide range of companies...

Design of Submarine Pipelines Against Upheaval Buckling
This paper describes part of a comprehensive joint-industry project on upheaval buckling. It develops a semi-empirical simplified design method and detailed design methods based on a new numerical analysis,...

A Preliminary Case for the Existence of Hurricane Alleys in the Gulf of Mexico
A review of hurricance intensity in the Gulf of Mexico suggests there are two alleys where hurricanes are roughly 20% more intense than elsewhere. This paper develops a physical basis for the alleys using...
