| Abstract: | Research on carrying capacity evaluation measures of highway bridges is a cosmopolitan issue for discussion, which is still in the research period.Based on the practical application, the paper analyses and compares the evaluation measures of appearance inquisition, account and load test of bridge state evaluation measures in China and United States. The paper also makes a particular comparison on the evaluation levers setting, the formula, the adjust coefficient and so on, and puts forward some improving suggestions based on the analysis results and the actually practical effect and experience. |
| Keywords: | bridge carrying capacity evaluation measure contrast and research |
