Model Study of a Hurricane Surge Barrier Gate Valve
Physical model studies were conducted to determine the hydraulic performance of a unique vertical butterfly-gated structure. These studies were also used to determine the torque on the...

Rock in the Limestone Regions of the Southeastern United States
Problems often arise in the shaft drilling industry in the Southeast. The karst areas in this region have certain situations found in few other places. Erratic boulders and limestone pinnacles...

The Use of a Deep Shaft for the Waste Water Treatment Plant of Orgamol SA
The first version of a new deep aeration system has been built for Orgamol SA, a chemical plant in the Rhone valley, Switzerland. Construction, operation and oxygen transfer mode of the...

Design, Selection, and Application of Disc Cutters in Hard and Abrasive Rock
Disc cutters have been used on tunnel boring and shaft boring machines for many years and are a proven method to bore hard rock. This paper will study the important parameters which effect...

Probabilistic Evaluation of the Performance of Axially Loaded Bored Piles
Probabilistic evaluation of single slender elastic elements, bored piles, in a multi-layered soil system without noticeable displacement of the soils are considered. The numerical analyses...

Mean Square Stability of Linear Gyroscopic Systems Under Combined Harmonic and Stochastic Excitations
This paper examines the mean square stability of linear gyroscopic systems under both harmonic and stochastic parametric excitations. The intensities of both excitations and correlation...
