Annual Performance Survey of Reinforced Concrete Pipe Culverts (5th.)

摘要

In order to comply with the request of BPR Circular Memorandum 22-42 dated November 12, 1959, that a number of reinforced concrete pipe culverts be designed and installed in accordance with outlined procedures, and be inspected periodically and evaluated, a number of installations were made. The culverts selected for yearly inspections are in Jefferson, Shelly, Franklin, Clark, Montgomery, Scott, Grant, and Kenton Countries. Each culvert was inspected once each summer during the five summers from 1960 through 1964. The report summarizes the design and construction factors and the performance for each pipe inspected during the five summers. Findings of the first yearly inspection resulted in widespread alarm; and, as a consequency, great emphasis was placed upon rigid inspection of all reinforced concrete pipe installations. The final conclusion was that the design and installation criteria of BPR was valid but it was important to adhere to the prescribed bedding details. (Author)
