| Abstract: | In order to determine the maximum load, the catenary fixed arch bridge with 140 meters span was respectively computed under the action of vehicle load and heavy-cargo transportation based bridge design specifications. The result according with the engineering practice shows that it has the good practical application value and prospect, and its methods and conclusions can be a reference for other similar projects. |
