| 摘 要： | 以某连续箱梁桥加固为工程背景,通过对加固前、后两次荷载试验获得的现状数据进行对比分析,对加固效果进行了评价。同时引入＂应力储备系数＂概念,为以后的预应力连续箱梁桥的加固荷载试验提供借鉴。 |
| 关 键 词： | 预应力连续箱梁桥 荷载试验 桥梁加固 应力储备系数 |

| Abstract: | Combining the continuous box beam bridge reinforcement as the engineering background,via load test data before and after the reinforcement,the article makes contrast analysis for the result and evaluates the reinforcement effect.Meanwhile,the article introduces ＂stress repertory coefficient＂ concept,which presents references for the load test of continuous box beam bridge reinforcement. |
| Keywords: | continuous box beam bridge load testing bridge reinforcement stress repertory coefficient |
