| 摘要： | Recent technological advances in the global positioning system (GPS) have made it a cost-effective tool for monitoring the safety and performance of bridges. Advances in GPS receiver technology and data-processing software make GPS a valuable tool that can be integrated into an automated continuously operating system. A prototype GPS-based bridge monitoring system has been developed for the Federal Highway Administration's nondestructive testing and evaluation program. The system has been tested successfully on two major highway bridges, and its design is being customized. This article describes the two system architectures for structural monitoring with GPS--fixed network sensors and mobile sensors. Two implementations of these systems are discussed. The authors predict that structural monitoring will continue to increase in importance, and with new tools, will decrease in cost. A sidebar explains the differences in navigation and surveying applications using GPS. |
