| 摘要： | A comprehensive study was initiated at the Federal Highway Administration's Nondestructive Evaluation Validation Center to study the reliability of visual inspection of highway bridges. The general objective of the study was to provide an overall measure of the reliability and accuracy of routine and in-depth inspections and to study the influence of human and environmental factors on inspection reliability. Two important components of this study were a state-of-the-practice survey and a field investigation. Unbiased measurement of the human and environmental factors was essential to establishing accurate and meaningful cause-effect relationships with the inspection results. It is envisioned that the results of this study will help define the accuracy of normal bridge inspection practices and will help bridge owners allocate and use bridge inspection resources more effectively. |
