15 Mile Road/Edison Corridor Sewer Tunnel Failure Study, Detroit Area, Michigan

Description: Partial abstract: "The study consisted of field and laboratory investigations, construction evaluation, and geotechnical and structural analyses to determine the cause(s) of distress and failure of a 2600-ft section of 12-ft 9-in. diameter concrete-lined sanitary sewer tunnel in the Detroit, Mich., area. [...] The report includes summaries of all pertinent construction records, results of all pertinent past and current field and laboratory tests on construction and geotechnical materials, and detailed geotechnical and structural analyses based on observed conditions and measured parameters."

Acoustic Flowmeter Prototype Evaluation Tests

Description: Summary: "Prototype tests of an acoustic flowmeter system were made in a 24-ftdiam power penstock at Oahe Dam to evaluate the system prior to permanent installation in the outlet works at Summersville Dam. Comparative discharge measurements included acoustic, penstock pressure-momentum (Gibson), turbine model test ratings, scroll-case pressure differential (Winter-Kennedy flowmeter), and surge tank volume changes. The acoustic flowmeter measurements were very consistent and many of the comparisons were within 1%. The location of the measuring section for a single-path acoustic flowmeter must be selected to give a known or measurable relation between the flow pattern of the whole section and that along the acoustic path" (p. xi).

Airfield Pavement Evaluation: Report Number 8, Ardmore Air Force Base, Ardmore, Oklahoma

Description: Summary: results of flexural strength, CBR, and plate bearing tests, moisture and density determinations, mechanical analysis, and Atterburg limits tests conducted on the pavements, bases, and subgrades of the various landing facilities at this airfield are used in this report to evaluate the load-carrying capacity of the pavements with respect to various landing-gear assemblies and operational-life categories.

An Analytical Model for Predicting Cross-Country Vehicle Performance, Appendix B: Vehicle Performance in Lateral and Longitudinal Obstacles (Vegetation), Volume 1: Lateral Obstacles

Description: First part of an appendix that accompanies a study meant to develop a model for predicting the cross-country performance of military vehicles in various conditions. This volume describes a segment of tests to determine the ability of vehicles to negotiate lateral obstacles (e.g., trees, boulders, holes, mounds, etc.).

An Analytical Model for Predicting Cross-Country Vehicle Performance, Appendix D: Performance of Amphibious Vehicles in the Water-Land Interface (Hydrologic Geometry)

Description: Summary: "Forty tests were conducted with two amphibious tracked vehicles and one amphibious wheeled vehicle at Eglin Air Force Base, Fla., and near Khon Kaen, Thailand, to determine the vehicles' capabilities for exiting closed bodies of water. Empirical relations, based on the data collected in this study and in previous studies, are presented to support the conclusions that performance of amphibious tracked and wheeled vehicles (in terms of "go-no go") in the water-land interface can be correlated with soil strength (expressed as average cone index of the 0- to 6-in. soil layer), and that the slope-climbing ability in the water-land interface of the tracked vehicles tested compares favorably with that of the same vehicles operating on land surfaces of similar soil composition and consistency" (p. ix).
