The Soil-Rock Boundary: What is it and Where is it?
A major issue in many areas of Civil Engineering practice is the boundary between earth materials that are defined as soil and those that are defined as rock. Designers, contractors, and...

The U.S. Office of Surface Mining (OSM) Proposed Strength-Durability Classification System
Federal regulations for the surface mining of coal stress proper design and construction of stable waste rock disposal areas. A key to the long-term stability of these excess spoil fills...

Design and Construction of Boat Launching Ramps
Although boat launching ramps are not 'high tech' facilities compared to many other types of waterfront construction, there is a continuing void of knowledge,...

System and Utilization Study of Japanese Experiment Module for International Space Station
The paper briefly reviews the overall system study of Japanese Experiment Module (JEM) which consists of Pressurized Module, Exposed Facility and Small Remote Manipulator System (RMS)....

Design Considerations for a Ceramic Fabric Radiator
The design of an Advanced Ceramic Fabric (ACF) thermal management device for use in both interplanetary and near-earth space must consider several important aspects of the environment....

Alternative Wall and Reinforced Fill Experiences on Forest Roads

Cellular Sheetpile Bulkheads

Numerical Modeling of a Trench Fill and Scour
The sediment fill and scour in a dredged trench was numerically simulated by the nodal-collocation finite element method and an explicit scheme. The one-dimensional unsteady sediment-laden...

Strength of Compacted Frozen Fill After Thawing

A Seawall for Sea Mammals
With glass walls only 75 ft from Lake Michigan, an aquarium addition demanded solid seawall protection. Yes, in a strange twist of logic, the first step in creating a whale habitat for...

Diatomaceous Soils: A New Approach
Diatomaceous soils are formed over long periods of time when the skeletal remains of plankton and other single-celled marine creatures sink and accumulate in lakes, estuaries and oceans....

Orchestral Maneuvers
Symphony Towers is an H-shaped superstructure that straddles Symphony Hall in downtown San Diego. The $143 million project is a 34-story office building to the south of the hall and a...

Terminal 91 Short Fill Monitoring Results: Insights for the Future of Contaminated Dredge Material Disposal

Deep Soil Mixing at the Jackson Lake Dam
The Jackson Lake Dam was constructed in 1917 in the Grand Teton National Park near Jackson, Wyoming. The dam was a hydraulic fill placed on a natural alluvium and outwash foundation. The...

Settlement Characteristics from Insitu Tests in Flyash Structural Fills
Flyash from the Baltimore Gas and Electric Company's plants was used to construct structural fills in thickness ranging from 5 to 25 feet (1.5m to 7.6m). Several warehouses...

Analysis of Drilled Shafts in a Deep Fill
A deep fill of varying thickness will settle with time and will also exhibit a horizontal component of movement. Drilled shafts that are installed in the fill to support a structure must...

Beach Replenishment Along the U.S. Coast of the Gulf of Mexico

Assessment of a Two-Layer Beach Fill at Corpus Christi Beach, TX

Prediction of Beach Fill Response to Varying Waves and Water Level

The CADD Landfill
Designing landfills with CADD, engineers have reduced cut and fill calculations from two weeks to two days. Aerial surveys arrive on magnetic tapes and are loaded into computers by in-house...
