| 摘要： | The opening of soil voids below pavement caused by the failure of culverts and drainage piping creates a safety hazard. More accurate and cost-effective new non-destructive approaches are sought to inspect roadways. The study focuses on the experimental validation of rapid aerial infrared thermography (AIR_T) and unmanned aerial systems (UASs) for detecting soil voids and assessing the conditions of culverts and drainage piping underneath public roadways. Specific goals include: Determine the accuracy of IR imaging for field inspections to detect soil voids as a function of depth and to detect underground structures; Characterize the smallest size and severity of defects that can be detected with IR thermography; Define operational problems associated with its field deployment and suggest operating procedures to optimize the use of IR imaging on UAS platforms; Outperform currently used techniques such as visual inspection and GPR. |
