| 摘 要： | 基于桥梁运营状态监测得到的应变历程数据,通过对测点影响线形状的较深入分析,建立了识别过桥车辆荷载的一种BWIM方法———“单峰锐度法”。结合实例的分析表明该方法能够较精确识别稀疏交通状态下车辆数量、大小、作用位置,并能推求影响线内多车作用下的荷载。 |
| 关 键 词： | 车辆荷载 识别 影响线 应变历程 |

| Abstract: | Based on the strain history information obtained from monitoring of bridge operation state,and through detailed analysis of influential line shapes of measurement points on the bridge,a BWIM(Bridge Weight in Motion) method,the single-acme acutance method that can identify passing vehicle load,is established.The still further analysis in connection with several actual examples reveals that the method can fairly accurately identify the numbers,sizes and action positions of the passing vehicles on the bridge in the state of sparse traffic volume,and can derive load under multiple vehicle action within the influential lines. |
| Keywords: | vehicle load identification influential line strain history |
