| 摘 要： | 桥梁结构剩余寿命的预测对结构的安全使用具有重要指导意义。服役桥梁结构的抗力随时间逐渐退化,车辆荷载也是随时间变化的随机变量。本文采用时间离散法计算结构时变可靠指标,进而推知结构的剩余寿命。 |
| 关 键 词： | 桥梁 剩余寿命 时间离散法 时变可靠度 |

| Abstract: | The prediction on residual service life of bridge structure has the important instructing meaning for the safe use of the structure. The structural resistance of the bridges under service is gradually degraded with the time, and the vehicle load is also changed with the time variability. The article uses the time-discrete method to calculate the time-variable reliable index of the structure so as to deduce the residual service life of the structure. |
| Keywords: | bridge residual service life time-discrete method time-variable reliability |
