| 摘要： | A twin bridge failure at Arroyo Pasajero near Coalinga, California gave the California Department of Transportation an opportunity to install and test a temporary railroad flatcar bridge. The concept of using railroad flatcars as bridges is not new; however, the use of railroad flatcars as modular, reusable bridges is new. The entire assembly is modular and versatile as well as structurally strong and able to pass dynamic analysis. This article describes the temporary bridge at Arroyo Pasajero, providing design and construction information. The author reports that transportation agencies must remember to include hauling of flatcars, field welding, and dismantling to estimates of overall cost. |
