| 摘要： | This study is a contribution to the Heated Bridge Technology Program established in 1991 under the Intermodal Surface Transportation Efficiency Act. The goal of the program was to find durable and environmentally friendly heated bridge technologies for ice and snow removal. The purpose of this study was to evaluate the first heated bridge built in Virginia. The bridge is on Route 60 over the Buffalo River in Amherst County. The project was monitored from its construction in 1995 through winter operations terminating in spring 2000. Data were collected remotely using an electronic datalogger interfaced with various temperature and environmental sensors. In addition, an infrared camera was used to examine heat distribution across the bridge deck. The results of the study demonstrated that heat pipe technology could provide a feasible option for heating decks. However, substantial problems were encountered in getting the system to perform as designed. It appears that the control aspect of this technology requires additional improvements to ensure reliable operation under field conditions. |
