| 摘 要： | 针对桥梁在营运过程中,理论影响线与实际影响线存在偏差的客观情况提出研究。以梁式桥为对象,在基本原理探索的基础上,推导出递推迭代实测桥梁影响线的公式,并阐述了如何应用。文章还进行了采用递推迭代法实测桥梁影响线技术的客观可靠性分析,结合实桥具体介绍了如何应用递推迭代法实测桥梁影响线技术来评定桥梁实际承载力。可靠性检验表明,该技术具有可靠、直观、经济、实用的特点,可望在今后桥梁承载力评定中发挥重要的技术、经济、社会效益。 |
| 关 键 词： | 递推迭代 实测影响线 承载力评定 |

| Abstract: | During bridge operation,there exists some difference between the theoretical and practical influence lines,taking beam bridges as an example,the authors induce a formula for recurrence iterative test of bridge influence line on the basis of rudimental principles and presents how to apply the proposed theory to analyze and evaluate the actual bridge bearing capacity.The experiments show that the technique is reliable,intuitionistic,economical,and practical. |
| Keywords: | repeating-recurrence practical influence line bearing capacity evaluation |
