Control of Gas Flow from Sanitary Landfills
Organic refuse materials deposited in a sanitary landfill undergo a process of decomposition that generates various gases, e.g., methane, carbon dioxide, hydrogen sulfide, etc., as well...

Research Activity and Needs in Engineering Surveying
Engineering surveying is a basic, yet most vital, element of civil engineering design and construction. Recent concern for conservation has spurred an accelerated research activity in...

Improving Your Writing
This article gives tips for improving your writing. It focuses on the writing of the magazine article, since the same principles are applicable to writing letters, memos, engineering reports....

Interstate Highway System
Eventually to cost nearly $90 billion, the Interstate Highway System will connect all U.S. cities of 50,000 and larger, eventually carry 25% of all highway traffic. The article traces...

OTA: Mixing Technology and National Goals
The need has developed for a broad multidisciplinary capability to assess technology, that is, to develop valid information about probable consequences, beneficial, harmful, or uncertain....

A Comparative Study of Structural Response to Explosion-Induced Ground Motions
The report provides detailed information about the responses of actual structures to loads, both static and dynamics, which can be expected to occur during their service life. The characteristics...

Vibrations During Construction Operations
The subject of earth vibrations related to construction operations is examined in perspective. Comparison of conventional demolition methods versus demolition by explosives is considered....

Investing in Urban Bicycle Facilities
A new mode of transportation and recreation—the bicycle—has explosively entered the public's consciousness. Accompanying this phenomenon has been a rash of problems including...

A Study of Damage to a Residential Structure from Blast Vibrations
A primary objective of this test project was to study, under carefully controlled conditions, the effects of earthborn blast vibrations upon a residential structure. Another objective...

Seismic Effects on Earth Dam from Explosion
The motion of Rifle Gap Dam, a 120-ft (37-m) high, 1,500-ft (460-m) long rolled earth fill dam, was measured during its response to the ground motion effects produced by a deep underground...

Integrity and the Ecological Crisis
Population pressures represent the ultimate force driving all organized societies to exceed their resources, and unless that force is brought under control, nothing else can matter for...

Slope Analysis for Explosive excavations

Expressway Rapid Transit
Chicago was the first city to apply the concept of integrated use of a right-of-way for both expressway and rapid transit, but actually the concept of a multimodal transportation corridor...

Propagation of Waves Generated by Underwater Explosion

Planning Implications of Urban and Rural Freeway Interchanges
Accessibility, traffic and the availability of developable land have been the volatile ingredients touching off the development explosion in the vicinity of the freeway interchanges. Zoning...

Photogrammetric Mapping of Craters from Small Explosions
The possible future use of nuclear explosives for large-scale excavation projects has led to small-scale investigation of cratering and ejecta mechanisms using chemical explosive charges....

Simulation of Waves by an Underwater Explosion
The properties of water waves produced by underwater explosions were studied in a test basin where the underwater disturbance was simulated by means of a rapidly withdrawn or immersed...

Shock Spectra Subsurface Nuclear Explosions
Equations are given for computing vertical and horizontal radial ground-stock spectra from an underground nuclear explosion. Parameters required are the yield of the explosion, the slant...

Knowledge of Sedimentation in Urban Environments
The population explosion, coupled with technological progress of the last century, has created megalopolis. Urbanization-suburbanization of America has changed the hydrology of affected...

Comparative Radioactivities from Nuclear Excavation
The chief potential value of nuclear excavation is in reduced initial cost. In addition to economic factors, however, practicality and safety of the nuclear method must be assessed for...
