The Microcomputer Explosion in Civil Engineering Firms
During the next five years, small and medium size consulting engineering firms will undergo many changes. The key changing force is the low cost ($2500 to $20,000) microcomputer. Already,...

Calorific Value of Wastewater Plant Sludges
Calorific values of wastewater plant sludges are best determined using an oxygen bomb calorimeter, an apparatus which is not readily available in many plants. Using a variety of sludges...

Simultaneous Airblast and Ground Motion Response
A single-degree-of-freedom approach is used to model structural response to superimposed airblast and ground vibration from conventional explosions. A method is used whereby the force...

Soil Pressures Due to Aircraft Loans
Soil pressure gages were installed in a crushed limestone backfill of a bomb damaged runway. Measurements were made due to static and dynamic aircraft, C-130 and F-4E, wheel loads. Static...

Product Liability and Professional Responsibility Risk Analysis

Optimization on Refuse Collection Systems
A solution to the vehicle routing problem for refuse collection in large cities is presented. The algorithm accommodates real world constraints and employs a combined heuristic and computer...

Hazardous Waste Management — RCRA Compliance: An Army Ammunition Plant

A Home for the Navy's Trident Subs
On 7,000 acres near Seattle, Washington, sits the largest military base constructed in the U.S. since World War II. The Navy's multimillion-dollar Trident project, a combination...

Surface-Mining Legislation and Regulation
This paper highlights the relevant provisions of The Surface Mining Control and Reclamation Act of 1977 (PL 95-87) and provides an overview...

Rockfill Quarry Experience, Ord River, Australia
The main feature of the Ord River Project in Australia is a rockfill dam constructed by Dravo Corporation. Quartzite rock was quarried adjacent to the damsite using coyote blasting methods...

Remote Sensing in Archaeological Sampling Designs
The recent explosion of archaeological research, necessitated by Federal legislation and carried out in conjunction with large construction projects, has produced serious problems for...

Mount St. Helens Eruption—Impact and Civil Engineering Response
The May 18 eruption of Mount St. Helens in Washington state, estimated to have the energy equivalent of a 20 to 50 megaton atom bomb, did tremendous damage. It destroyed an estimated 160...

Timber Trestle Carries Air Force Bombers
A 12-story high timber trestle, built at Kirtland Air Force Base near Albuquerque, N.M., is the world's largest all-wood structure in terms of board-feet of timber used. Its...

Disposal of Hazardous Toxic Munition Waste

Earthquake Simulation Using Contained Explosions

Methane Migration Around Sanitary Landfills
Mathematical models have been developed to predict methane migration around sanitary landfills. The methane gas that is generated during the decomposition of refuse constitutes an explosion...

Lateral Loads on Power Boilers
The structural section of power-boiler specifications should include lateral-force design criteria to minimize the possibility for critical damage and resulting financial loss during a...

Local Effects of Tornado-Generated Missiles
Nuclear power plant facilities and many other structures need protection against missiles generated by tornadoes and explosions. Empirical formulas are presented to determine the local...

Incipient Joint Motion Due to Spherical Explosion
The problem of incipient joint/fault motion due to a spherical explosion in an infinite homogeneous isotropic rock mass is considered analytically. The mechanical response of intact rock...
