| 摘要： | Understanding the factors that in uence the performance of a bridge is a very important topic and due to the complexity of bridges, this is rather a hard task because there are multiple factors, which can in uence the performance of a bridge. These factors can include design practices, construction quality, environmental factors, and truckload. Sister bridges are parallel bridges that generally have identical design and construction quality. The main difference between these structures is often the load factor; therefore, there is a great opportunity for studying these structures. Within this research project, condition assessment of two sets of sister bridges in Virginia will be conducted using manual NDE technologies as well as the robotic platform RABITTM. The following NDE methods will be used in both the automated and manual testing: Impact Echo, Ultrasonic Surface Waves, Ground Penetrating Radar and Electrical Resistivity method. The data collected from all the technologies will be analyzed and the results presented in terms of condition maps and calculated condition indices. |
