| 中文摘要: |
| 既有桥梁承载力评定方法的研究是一个世界性的课题，目前还处于研究阶段。本文从实际应用出发．对中美两国桥梁状态评定中的外观调查法、检算评定法和荷载试验法进行了调查、比较和评述，从评定等级设置、公式形式、折减系数等多个方面展开详细对比，并根据比较分析的结果，结合实际应用的效果和体会，对其中的一些方法提出了改进建议。 |
| 英文摘要: |
| 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. |
